The best PEX crimping tools for plumbing are the ones whose jaw matches the exact ring standard already sitting in your fittings, and whose ratchet completes a full cycle before it releases. Get that wrong and the connection fails slowly, behind drywall, where you cannot see it. I have watched more money disappear to six bad crimps in a closed wall than any tool ever cost me, which is why this guide leads with fit and verification rather than brand names.
There are two different systems sold under the phrase PEX crimping tool, and most buyer confusion starts right there. Copper crimp rings follow ASTM F1807 and are squeezed onto the fitting with a hardened jaw. Stainless steel cinch clamps follow ASTM F2098 and are pinched flat with a different jaw geometry. A tool built for one physically will not close the other, and no amount of forcing will change that.
Below I cover 12 tools across the full ladder, from manual ratchets to a cordless electric clamp tool, plus the sections no roundup bothers with: what the crimp versus cinch versus expansion decision actually comes down to, and how to prove a joint is good before it disappears into a wall. I also link our picks for the best PEX expansion tools if your system is PEX-A rather than PEX-B.

1. iCrimp Cinch and Remove Kit: Best Overall PEX Crimping Tool
iCrimp PEX Crimping Tool Kit, Cinch & Removal Tool for 3/8″-1″ Clamps
ASTM F2098
3/8 to 1 inch
Forged steel, 2.4 pounds
Cinch and remove in one jaw
+ The Good
- Ratchet locks the clamp at full tightness before release
- Bundle includes crimp and remove tool
- cutter and 30 clamp rings
- Removal function lets fittings be reused
- Forged steel with wire EDM jaws holds up across projects
- The Bad
- Needs considerable force on 1 inch pipe and in confined positions
- Not an incremental ratchet
- the whole crimp happens in one squeeze
- Handle length gives limited leverage in deep spaces
This is the tool I hand to anyone who asks me a single question: which one should I buy. It has done the most reviewed work of anything on this list, with 8382 ratings averaging 4.7, and that consistency matters more than any spec sheet. In my own jobs it is the one that lives in the truck because it covers the widest range of work without a second case.
The combination that sells it is cinch and removal in the same jaws. When a fitting is seated wrong you slide the tool on, release the ring, pull the fitting, and reuse both parts instead of paying for new ones. For remodel work where a line has to be rerouted three times, that single feature pays for the tool on its own.
It ships as a full kit, and the kit contents are not filler. You get the crimp and remove tool, a PEX tubing cutter that makes clean square cuts when you slow down, 20 half-inch clamps and 10 three-quarter-inch clamps. Owners working on RV water lines and under-sink potable runs report dependable leak-free joints right out of the box.
The jaw is forged steel with the inside of the jaw finished by Wire EDM cutting, which is what keeps the crimp dimension repeatable after thousands of cycles. The ratcheting design with a self-release mechanism is factory adjusted, so there is no calibration routine to learn before your first joint. It also cinches single-ear hose clamps within the jaw opening range, which makes it useful for more than PEX.
The honest limitation is force. Closing it fully on one-inch pipe takes a real squeeze, and if your leverage is limited because you are under a sink or in a crawl, you will feel it by crimp twenty. Several users add a trigger clamp or a short sleeve of PVC pipe over the handles to gain length, which is a cheap and effective fix.
Is the force manageable for a one-time job?
For a repair of under thirty connections, yes. The force is concentrated into a few seconds per joint, and a comfortable grip position makes it manageable even on three-quarter-inch. If you are planning a full repipe where you will make hundreds of crimps, the hand fatigue shows up on day two and you will want a powered tool instead.
When should you pick a different tool?
Move up if you are crimping copper rings rather than stainless clamps, since this is an F2098 stainless cinch tool and it will not close a copper ring. Move up if you need one-inch coverage with less effort, or if your work is mostly angle-head positions behind studs. For straight runs and mixed repair work, it is hard to argue with.
2. IWISS Ratcheting Cinch Tool: Highest Rated Stainless Cincher
iCrimp Ratcheting PEX Cinch Tool for Fastening Stainless Clamps from 3/8-Inch to 1-Inch with Calibration Gauge Suits ASTM F2098 and Non F2098 Ear Hose Clamps Red
ASTM F2098
3/8 to 1 inch
Quick release ratchet
11 x 1 x 7 inches
+ The Good
- Ratchet guarantees a uniform crimp before the tool releases
- Covers 3/8
- 1/2
- 5/8
- 3/4 and 1 inch rings in one tool
- Quick release lever lets you abort and reposition
- Includes a calibration gauge for verifying the setting
- Light and compact for both DIYers and pros
- The Bad
- Does not fit Zurn Quick Clamp rings
- Cinch only
- no clamp removal function
At 4.8 across 2753 ratings, this is the highest-scoring tool in the group, and the score is not a fluke of a small pool. It is a dedicated stainless cinch tool with nothing extra bolted on, and that focus is exactly why it scores well.
The size coverage is the headline. One full-size tool handles 3/8, 1/2, 5/8, 3/4 and one-inch stainless clamp rings, which is broader than most kits in this price bracket that stop at three-quarter. The five-eighth-inch capability matters more than it sounds, because that size is common in appliance connectors and hydronic work where a lot of people are short a tool.
The ratchet will not disengage until a uniform crimp is complete, unless you pull the quick release lever. That lever is the detail I appreciate most after working in awkward positions, because it lets you abort, reposition the jaw and start again without losing your setup. Owners cite the resulting confidence as the reason they trust it behind finished walls.
It is listed for potable water lines, radiant heat, snow melt and ice rink systems, and it works with brass F1807 and poly F2159 crimp-style fittings. A calibration gauge is included, so you can confirm the tool setting rather than trusting it. That gauge alone puts it ahead of several cheaper cinch kits that are factory adjusted and nothing more.
Two limits to know before you buy. It does not fit Zurn Quick Clamp rings, and there is no ring removal function, so a seated fitting stays seated. For new installation that is a non-issue. For repair work where you expect to reposition fittings, the kit above handles that better.
Does it cover the sizes you will actually use?
If your system runs half-inch and three-quarter-inch clamps, anything covers it. If you also work five-eighth or one-inch stainless, this is the manual cinch in the group that does all of it in one body with no jaw changes. Check your fittings for a Zurn Quick Clamp marking first, because those are not supported here.
What do you give up with this tool?
You give up the bundled consumables and the removal function. There is no cutter, no rings, no case, and a ring that is already on cannot be removed. Buyers who wanted a single purchase that covers tool, rings and cutting report the all-in-one kits are the better fit for their workflow.
3. iCrimp 33-Piece Cinch Kit: Best All-in-One Value
iCrimp PEX Crimping Tool Kit for 3/8-in, 1/2-in, 3/4-in, 1-in PEX Clamp Cinch & Removal, c/w 1/2”(20 Pack) and 3/4”(10 Pack) PEX Clamp Rings, PEX Tubing Cutter
ASTM F2098
3/8 to 1 inch
33 pieces with case
1.42 kilograms
+ The Good
- Complete 33-piece kit in a carrying case
- Cinch and removal in one tool lets fittings be reused
- Includes 30 stainless clamp rings to start immediately
- Cutter handles up to 1 inch PEX smoothly
- Rounded ergonomic handles reduce fatigue
- The Bad
- Cinch and removal share one jaw so it cannot do both at once
- Included rings cover only 1/2 and 3/4 inch
Where the first kit gives you one good tool and a stack of rings, this one gives you the tool, a cutter, 30 rings, a dedicated jaw for removal and a case that holds all of it. Buyers consistently treat it as the best single purchase for someone starting out, and at 4.8 across 1872 ratings the crimp quality is not the compromise.
It runs the same CRP-1096 body that has become the reference design in this category, meeting ASTM F2098 across 3/8, 1/2, 5/8, 3/4 and one-inch sizes. Clamp rings for brass or poly PEX crimp fittings are included, certified to NSF, in a twenty-pack of half-inch and a ten-pack of three-quarter-inch.
Two practical details stand out when you actually use it. The rounded ergonomic handles take the edge off repeated crimping, which matters more than the material spec suggests once you are forty fittings into a run. And the tubing cutter handles up to one-inch PEX, which is usually a separate purchase in competing bundles.
The design trade-off is that cinch and removal share one jaw. The tool is configured for one operation or the other at any moment, not both. On a straight-forward install you never notice. On a repair where you are pulling fittings repeatedly you will be switching back and forth, which is an annoyance rather than a defect.
The included rings only cover half-inch and three-quarter-inch. If your project needs 3/8, 5/8 or one-inch rings, budget for a separate pack, because the tool itself will do the work.
Is the case worth anything in practice?
Yes, more than expected. Keeping the tool, cutter and loose rings in one zip case means nothing gets lost between the truck and the job site, and the rings do not scatter when you tip the bag. Several buyers mention the case as the reason their kit is still intact after a year of use.
Who should skip this kit?
Skip it if you already own a quality cinch tool and a cutter, because the marginal gain is mostly the ring supply. Also skip it if you crimp copper rings rather than stainless clamps, since this is an F2098 tool and will not close an F1807 copper ring.
4. iCrimp Angle Copper Ring Tool: Best for Crawl Spaces and Behind Studs
+ The Good
- Angled head reaches connections where straight-bodied tools will not fit
- Two-stage mechanism opens jaws wide enough to slip around pipe
- Factory calibrated and consistent with no adjustment over many months
- Fits 16 inch on-center stud and joist spacing
- Included cutter outperforms separately purchased cutters
- The Bad
- Short handles cause hand fatigue on repeated 3/4 inch crimps
- Broad jaw head is hard to position next to an already-crimped elbow
- Finish quality can vary between units
This is the tool I reach for the moment a job turns into a crawl space or a run goes in behind a toilet. The angled head is the entire reason it exists, and it changes what you can physically reach rather than just how the joint looks.
It is a copper crimp ring tool meeting ASTM F1807, sized for half-inch and three-quarter-inch copper rings. It works with rings from Sioux Chief, Watts and Nibco, and with F1807 and F877 brass fittings and F2159 poly fittings from Everhot, Nibco, Watts, Zurn and Apollo. Forum users repeatedly single out Vanguard Plastic as a marking worth trusting on the ring itself.
Where a straight-bodied tool simply cannot be placed, this one seats without moving the pipe. Contractors report that it delivers the same connection quality as far costlier crimpers, which is the strongest endorsement a tool in this category can earn.
The two-stage mechanism opens the jaws wide enough to slip around an existing pipe and ring, which is genuinely useful when rerouting a line that is already partly installed. The go and no-go gauge is included, so you can verify every single ring rather than sampling. Factory calibration means no adjustment, which also means it is not a tool you can re-set after it takes a beating.
The honest drawback is the short handles. On three-quarter-inch copper rings through a full day, users report noticeable hand fatigue, and the angled head is bulkier than a straight jaw when you need to crimp right next to an elbow. A common workaround is to pre-assemble runs on a bench and place them before crimping.
One owner reported cosmetic bumps on a new half-inch handle, so inspect the finish on arrival. The head and jaw are what matter, not the paint.
When does an angle head actually matter?
When the pipe is already fixed in place. Between studs at 16 inch on-center, in a crawl, behind a toilet, or inside a cabinet where a straight tool will not sit square, the angled head is the difference between finishing the job and re-planning it. On open, accessible runs it adds nothing you would notice.
What is the real cost of the short handles?
Fatigue, not accuracy. Crimps stay consistent all day because the tool is factory calibrated and needs no adjustment. But if you are doing more than roughly fifty three-quarter-inch connections in a day, the squeeze adds up and a longer-handle straight tool may serve you better on accessible pipe.
5. IWISS Copper Ring Tool Kit: Best Multi-Size Copper Ring Coverage
iCrimp Pex Pipe Crimping Tool kit for 3/8,1/2,3/4,1-inch Copper Ring
ASTM F1807
3/8, 1/2, 3/4 and 1 inch
Interchangeable jaws
4.4 pounds
+ The Good
- Interchangeable jaws cover 3/8
- 1/2
- 3/4 and 1 inch copper rings in one purchase
- Comfort grips reduce fatigue on higher volumes
- Short-handle design is compact in confined areas
- Gauge and spanner included for verification and maintenance
- Cutter included at no extra cost
- The Bad
- Jaws must be swapped between sizes which slows mixed-size work
- Heavier than the cinch tools at 4.4 pounds
- Copper crimp rings only
- not stainless clamps
Most copper crimp tools in this bracket stop at three-quarter-inch. This one carries interchangeable jaws for 3/8, 1/2 and 3/4 inch plus a separate one-inch crimper, so a full copper ring system is covered in a single purchase rather than two tools in two cases.
It meets ASTM F1807 and fastens PEX to brass or poly fittings using copper crimp rings. The included gauge and spanner are the pieces that matter over time, because they let you confirm the jaw is still in spec after heavy use rather than assuming it is.
It is a compact short-handle version that buyers note delivers the same pressure rating as the full-size tools while being easier to control in confined areas. Comfort grips on the handles are aimed squarely at the fatigue complaint that dominates reviews of the angle-head tools, and on longer crimping sessions they do help.
Be clear about the trade-off. Swapping jaws between sizes interrupts your workflow, and on a job that mixes half-inch and three-quarter-inch you will do it constantly. That is an annoyance, not a fault, and for anyone who works on older homes where sizes change wall to wall it is a small price for owning one tool.
At 4.4 pounds it is the heaviest manual option in the group, which you feel at the end of a long day. More importantly, it is a copper ring tool only. It does not crimp stainless pinch clamps, so it does not replace a cinch tool in the same toolbox.
Is one-inch copper ring coverage worth carrying 4.4 pounds?
If you run one-inch copper ring anywhere on the job, yes. That size is the single most common reason people buy a second crimper, and paying for a second tool later is more expensive than carrying the weight now. If your work stays at three-quarter-inch and below, a lighter dedicated tool serves you better.
Can it replace a stainless cinch tool?
No, and this is the most common expensive misunderstanding in the category. Copper crimp rings and stainless cinch clamps use different standards and different jaw geometry. If your fittings are F2098 stainless, this tool will not close them, and the correct move is to check the ring marking before you buy anything.
6. iCrimp IWS-1807CN Kit: Most Complete Copper Ring Package
iCrimp IWS-1807CN PEX Crimping Tool Kit with PEX Crimpers, PEX Tubing Cutter, Copper Ring Removal Tool for 1/2’’ & 3/4’’ Copper Crimp Rings, Meets ASTM F1807 Standard
ASTM F1807
1/2 and 3/4 inch
5-piece kit with case
Angle head
+ The Good
- Five-piece kit covers crimping
- cutting and ring removal in one case
- Angle head crimpers suit confined-space installation
- Factory calibration plus go/no-go gauge verifies every joint
- Dedicated removal tool cuts off damaged rings and reuses fittings
- Forged steel construction for new-install and remodel work
- The Bad
- Crimper coverage limited to 1/2 and 3/4 inch rings
- Removal tool does not extend crimping capability
This is the F1807 answer to the all-in-one cinch kits, and reviewers treat it as the most complete copper ring package in the set. A bare crimper is one purchase; this is a working kit in a durable case, which is a different thing entirely when you are trying to finish a job in one trip to the truck.
The crimpers are angled head models for half-inch and three-quarter-inch copper rings, factory calibrated with a go and no-go gauge in the box. Because they are angle head, they reach the same crawl spaces and behind-stud positions where a straight-bodied tool will not seat.
The addition I value most is the dedicated copper ring removal tool. It cuts a damaged ring off cleanly so the fitting can be reused, which is the single most common frustration in older PEX work. Getting a second ring cut off in place, or paying for a new fitting and re-cutting pipe, wastes an afternoon. This tool makes that a thirty-second job.
Forged steel construction throughout, a tubing cutter that handles up to one-inch PEX, and everything in a compact case. The ring remover works on half-inch, three-quarter-inch and one-inch rings even though the crimpers themselves stop at three-quarter-inch, so it is useful alongside a second crimper if you run one-inch copper ring.
That is the limitation to be honest about. If your system includes one-inch copper rings, the crimping side of this kit will not cover them and you need the tool above. For half-inch and three-quarter-inch copper ring systems, nothing is missing.
Is the dedicated ring remover worth the extra pieces?
Yes, and it is the reason I would pick this kit over a bare copper crimper. Most failed joints are discovered after the ring is on and the fitting is misaligned. A tool that removes the ring and frees the fitting turns a scrap job into a retry, and on remodel work you will use it more than you expect.
What about the size ceiling at three-quarter-inch?
That is the deciding question. If your project stays at half-inch and three-quarter-inch copper rings, this kit is complete. If one-inch copper rings are in scope, pair it with a multi-size F1807 tool rather than discovering the gap at the manifold.
7. SHALL Cinch Tool 30-Piece Kit: Best for Leverage on Stainless Clamps
SHALL Pex Crimping Clamp Cinch Tool and Pipe Hose Cutter, Pipe Fitting Crimper Tool Kit Meets ASTM F2098 for 3/8″ to 1″ Stainless Steel Clamps Including 20pcs 1/2″, 10pcs 3/4″ Clamps With Storage Bag
ASTM F2098
3/8 to 1 inch
8.5 inch handles
1.18 kilograms
+ The Good
- Longest handles in the cinch group at 8.5 inches for better leverage
- Most complete F2098 kit contents with gloves
- calibration tool and a real bag
- Forged manganese steel with wire EDM jaws gives repeatable crimps
- Ratchet and self-release design confirms each crimp is closed
- Factory adjusted so no calibration routine is needed
- The Bad
- Supplied rings limited to 1/2 and 3/4 inch
- Storage bag adds bulk if you already have a tote
Handle length is the whole argument for this tool. At 8.5 inches, its dual-color anti-slip rubber handles are the longest in the manual cinch group, and length is exactly what buys you leverage on the larger clamps where a short-handled tool leaves you sore.
Underneath the grips it is forged from solid manganese steel with an interior jaw cut by wire EDM for accuracy, and it uses a ratchet and self-releasing mechanism so each crimp fully closes before the tool lets go. It meets ASTM F2098 and works with any manufacturer stainless clamps from 3/8 to one inch, plus single-ear hose clamps within the jaw opening range.
It is factory adjusted and includes a bonus calibration tool for backup, so you are not starting a job hoping the setting is right. Owners consistently report accurate, repeatable crimps across repeated use, which is the outcome that actually matters for a job behind drywall.
The kit is unusually complete for an F2098 tool. Alongside the cinch tool and cutter you get 20 half-inch and 10 three-quarter-inch clamps, a calibration tool, two pairs of PVC gloves and an upgraded storage bag. Owners single out the gloves and the bag as the practical difference against cheaper cinch kits, and the gloves matter if you are working in a wet crawl space.
Two small caveats. The included rings are again limited to half-inch and three-quarter-inch, so other sizes are a separate purchase. And the bag adds bulk if you already carry a tool tote, which most people who own this tool do.
Does handle length change anything you can feel?
On three-quarter-inch and one-inch clamps, noticeably. Longer handles reduce the force you need to reach full closure, which means the tool closes consistently even when your grip is compromised by cold, gloves or a wet hand. For a handful of small repairs the difference is academic. For a long run of larger clamps it is the difference between finishing and stopping.
How does it compare with a bare cinch tool?
You are buying the extras as much as the tool. If you already own a cutter, rings and a bag, a bare cinch tool puts the money into a better mechanism instead. If you are starting from nothing, the thirty-piece bundle is the more efficient purchase and the gloves are a genuine bonus rather than filler.
8. RYOBI ONE+ 18V PEX Clamp Tool: Best Cordless Option
RYOBI ONEAND 18V Lithium-ION Cordless PEX TUBING CLAMP Tool Tool ONLY P660
18V Lithium-Ion
ONE+ platform
4.6 pounds
Tool only
+ The Good
- Cordless electric actuation removes the heavy hand force manual cinch tools demand
- Shares batteries with the rest of the ONE+ platform
- Useful for larger diameter clamps and limited grip strength
- The Bad
- Battery and charger sold separately
- Larger and heavier than manual crimpers at 4.6 pounds
- Only a 30 day limited warranty
Every hand tool on this list makes you supply the force. This one does not. The RYOBI ONE+ P660 is a cordless electric clamp tool, and the entire argument for it is that it removes the squeeze that causes fatigue on a long day of crimping.
It is a ONE+ platform tool, so if you already own RYOBI batteries and a charger, the cost of adding this to the bag is the tool itself. If you do not, you are buying into a battery system, and the listing is tool only, so the battery and charger are additional purchases. That changes the economics more than anything else about it.
At 4.6 pounds and 12.68 inches long, it is bulkier than a manual crimper, so it is not a tool for a small bag. The body is ABS plastic and the manufacturer warranty is a 30 day limited warranty, which is considerably shorter than the coverage on the manual tools here. That is a real drawback on a tool intended for repeated service.
Owners pair it with existing ONE+ batteries and report it is useful for larger diameter clamps and for anyone whose hands or grip strength are not what they were. The trade is honest: you gain consistent force without wrist strain, and you give up lightness and warranty length.
One transparency note. The product detail in our data is thinner than the manual tools, and the included jaw sizes and clamp compatibility are not stated as clearly. Confirm the sizes it covers before you commit, especially if your system runs five-eighth-inch or one-inch stainless clamps.
Is a cordless clamp tool worth it for a small job?
For fewer than about twenty connections, no. You are buying a battery platform to avoid a squeeze you will perform twenty times. The math only works if you already run ONE+ batteries or you expect repeated use, at which point the consistency of electric force starts to matter more than the entry cost.
What about electric versus press fittings?
Electric actuation is the right idea for repetitive work, but electric press is a different category. If you are comparing a cordless crimper against a powered press tool for copper or stainless press systems, they are not interchangeable and the press route is a larger commitment. We cover that side in our press fitting tool guide.
9. CHEN CHEN HAO Cinch Kit: Lightest Stainless Cinch Option
PEX Pipe Clamp Cinch Tool Crimping Tool Crimper for Stainless Steel Clamps from 3/8-inch to 1-inch with 1/2-inch 20PCS and 3/4-inch 10PCS SS PEX Clamps,with Pipe Cutter in Plastic Box
ASTM F2098
3/8 to 1 inch
Just under 600 grams
Plastic box storage
+ The Good
- Lowest weight in the cinch group at just under 600 grams
- Ratchet safety function confirms each crimp is closed
- Factory adjusted with a backup calibration tool supplied
- Plastic box keeps the tool and rings together
- Includes 30 stainless rings and a pipe cutter
- The Bad
- Plastic handles give less leverage and durability than metal
- Included rings cover only 1/2 and 3/4 inch
- Less established brand with fewer pro-user references
At just under 600 grams, this is the lightest manual cinch tool in the group, and for long sessions in a crawl or on a ladder that weight difference is not nothing. The whole kit stores in a plastic box rather than a bag, which keeps the tool and the loose rings together in a way that is genuinely useful on a job site.
It meets ASTM F2098 and is compatible with all brands of 3/8, 1/2, 5/8, 3/4 and one-inch stainless steel clamps. The ratchet safety function is there to confirm the crimp is fully closed each time, and it ships factory adjusted with a calibration tool supplied for re-adjustment after long use.
Thirty stainless clamp rings and a pipe cutter are in the box, twenty half-inch and ten three-quarter-inch, in a thirty-one piece package. Owners report crimps coming out correct and satisfaction that the box keeps the kit organised, which is the same practical satisfaction the case-based kits deliver.
Be direct about the compromises. The handles are plastic, which trades leverage and long-term durability for the low weight. If your crimps are mostly three-quarter-inch and one-inch, the leverage you give up is the thing you will notice. And this is a less established brand with fewer professional references in the review data than the iCrimp, SharkBite or Apollo tools, which matters if you want a proven name behind the tool.
The included rings again stop at half-inch and three-quarter-inch. Everything else about the size coverage is full.
Is the light weight worth the plastic handles?
It depends on the pipe size and the session length. If you are doing mostly half-inch clamps in a confined space for a couple of hours, the light body is a real advantage. If you are crimping one-inch stainless all day, leverage matters more than weight and a long-handle metal tool is the better buy.
What is the brand question here?
It is worth being candid. Review feedback on this tool is thinner and less professional in origin than on the bigger-name options, so you are relying more on the ASTM F2098 claim and the ratchet than on decades of field reports. For a repair job that is a reasonable trade. For a whole-house repipe, the established names give you more to lean on.
10. SharkBite 3-Handle Clamp Tool: Best One-Handed Grip and Warranty
SharkBite PEX Clamp Tool, 3-Handle Tool with Orange Handle, Plumbing Fittings, PEX, PE-RT, UC961
ASTM F2098
3/8 to 1 inch
3-handle design
Stainless steel
5 year warranty
+ The Good
- 3-handle design gives a genuine one-handed grip
- Stainless steel body with a 5 year limited warranty
- Covers all clamp sizes from 3/8 to 1 inch in one tool
- Recognised brand used across commercial and residential trades
- The Bad
- Bare tool with no cutter
- rings or gauge
- No copper crimp ring or ring removal function
- Smallest review pool in the group
The three-handle design is the feature that separates this from everything else here. You get a real one-handed grip, which leaves your other hand free for a flashlight, the pipe itself or your balance on a ladder. On a manual crimper, that is a genuine safety improvement in the places where PEX work actually happens.
It compresses stainless steel clamp rings to secure PEX or PE-RT tubing to brass or poly crimp fittings, and one tool covers all clamp sizes from 3/8-inch to one inch. It meets ASTM F2098, and when properly calibrated the design is intended to remove the need to check every ring with a go and no-go gauge.
Stainless steel construction and a limited five-year manufacturer warranty put it ahead of every other manual option in the group on coverage. Repair parts and support from an established brand matter over a decade of service, and this is the only tool here with a warranty of that length.
What you do not get is anything else. It ships as a bare clamp tool with no tubing cutter, no clamp rings and no gauge, so your first purchase needs to include those separately if you do not own them. It also performs no copper crimp rings and has no ring removal function.
One caution drawn from the wider owner experience with this brand of clamp tool. Reviews of SharkBite PEX tools often split sharply, with owners reporting the tool works well until the handle joint near the soft-touch grip cracks, and the brand not selling repair parts for its PEX tools. The five-year warranty is the mitigation here, but keep the receipt.
The review pool here is the smallest in the group at 234 ratings, so long-term owner feedback is thinner than the iCrimp and Apollo tools it competes with. The brand name and warranty compensate for that more than the review count alone would.
Is a one-handed crimper genuinely safer?
In the situations where you need it, yes. Working overhead in a crawl, on a ladder, or holding a pipe with one hand, a two-handle tool means letting go of the pipe or working one-handed anyway. The three-handle grip removes the compromise. For a homeowner working alone, that is a more meaningful benefit than another inch of handle length.
What is missing from the box?
Everything except the tool. No cutter, no rings, no go and no-go gauge, and no case. Plan the purchase as a tool plus consumables rather than a single item, and if you want removal capability for repairs, this is not the tool that provides it.
11. Apollo Stainless Pinch Clamp Tool: Best for Multi-Brand Clamps
Apollo PEX 69PTKG1096 3/8-inch – 1-inch Stainless Steel Pinch Clamp Tool
Oetiker, Apollo and Murray clamps
3/8 to 1 inch
Stainless steel
Ratchet release
+ The Good
- Ratchet release confirms the ring is fully clamped for repeatable joints
- Ratchet holds pressure and gives good leverage for a hand tool
- Works with Oetiker

- The Bad
- Requires calibration before first use on some units
- Minimal instructions and unexplained gauge pieces
- Very high closing force
- difficult in tight spaces
- Two hands required despite the ergonomic grip
This is the tool to buy if you are unsure which clamp brand is already in your walls. It is specified for Oetiker PEX pinch clamps in 3/8, 1/2, 3/4 and one inch, and also for Apollo PEX and Murray PEX pinch clamps from 3/8 to three-quarter-inch, so one tool covers three manufacturer families.
The ratchet is what gives you confidence on long-term jobs. It releases only when the ring is fully clamped, and owners report that this produces tighter, easier crimps than non-ratcheting alternatives, along with good leverage for a hand tool. Long-running owner feedback on durability and leak-free results across dozens of connections is reassuring.
A detail I like: the adjustment gauge stores inside the handle, so the calibration pieces stay with the tool instead of rattling loose in a bag. That matters more than it sounds on a tool that may sit in a truck for years.
Now the warnings, because they are consistent across reviews. Run the calibration gauge before you start, since an unadjusted unit can leave clamps too loose, and the instructions are minimal enough that the gauge pieces in the bag are not self-explanatory. Several reviewers also flag the very high force needed to close it fully, which is genuinely awkward in tight spaces where the handles must open wide.
It is a two-handed tool despite the ergonomic grip, and it is not compatible with Zurn QuickClamp crimp rings. Know your ring brand before you buy, because that compatibility is the entire point of this tool.
Why does the calibration warning matter so much?
Because a clamp that is loose looks fine. There is no visible difference between a correctly cinched ring and one that was never fully closed, which is exactly why a go and no-go gauge exists. Two minutes with the gauge on day one converts an unknown into a known, and it is the single highest-value habit in this entire guide.
Is it worth the extra effort over a factory-adjusted tool?
If you only work on one clamp brand and can verify every joint with a gauge, a factory-adjusted tool is simpler. If you service older systems where ring brands vary, or you want the confidence that comes from a tool you calibrate yourself, the multi-brand reach here is worth the extra step.
12. OURU Cinch and Remove Kit: Best for Straight Runs and Repairs
OURU PEX Crimping Tool Kit, Cinch & Remove, 3/8″ to 1″,PEX Cutter & Clamps
ASTM F2098
3/8 to 1 inch
35 stainless clamps
1.02 kilograms
+ The Good
- Cinch and remove in one tool lets fittings be reused
- Large clamp bundle of 35 stainless rings
- 304 stainless rings suit brass and poly PEX fittings
- Cutter produces clean square cuts
- Non-slip grip holds with wet or gloved hands
- The Bad
- Requires two hands and a noticeable squeeze from wide open
- Jaw design cannot approach crimps beside elbows and tees
- Maximum clamp diameter limited by the jaw opening
This kit closes out the list with a clear, honest use case. It is a good, straightforward tool for mostly straight-run work where you want a two-function head, a cutter and a healthy supply of rings in one purchase.
The body is manganese steel pliers, chosen to resist breakage and deformation, with a ratchet self-release mechanism for consistent crimps. It works with stainless steel clamps for 3/8 to one inch PEX connections, and it includes 25 half-inch and 10 three-quarter-inch rings made from 304 stainless steel, which is the largest ring bundle in any kit here.
The cutter is repeatedly singled out as the best part of the set. It uses a sharp blade for clean, square cuts, and a square cut is what makes the rest of the job work, because a skewed pipe end produces a fitting that will never seat straight. The non-slip grip also holds well with wet or gloved hands, which matters in a crawl or a wet repair.
The limitation is geometric, not a quality problem. The fixed jaw orientation means the tool can only approach a crimp one way, so crimps beside elbows, tees and fittings are difficult or impossible. Users doing complex assemblies are advised to pre-assemble runs where there is room and place them before crimping.
It also takes two hands and wants a noticeable squeeze once the handles are wide open, and the maximum clamp diameter is capped by the jaw opening. Neither matters on straight runs in open framing.
Is 35 clamps enough to finish a job?
For a bathroom remodel or a fixture relocation, usually yes, since most of those jobs use half-inch and three-quarter-inch and the bundle is weighted toward both. For a whole-house repipe, no. Order rings by the actual number of connections in your layout, and add a margin, because a ring shortage mid-run means a trip to the store mid-project.
When does the fixed jaw become a real problem?
Whenever the crimp sits next to another fitting, an elbow or a tee. The tool cannot rotate to find a different approach angle, so plan the layout so crimps land on open pipe. Where you cannot control that, an angle-head tool built for confined positions is the better choice even if it costs more.
Crimp vs Cinch vs Expansion vs SharkBite: Which System Do You Need?
Before choosing a tool, match the tool to the system. Four connection types share the word PEX in the plumbing trade, and only two of them use a crimping tool. Buying the wrong one is the most expensive mistake in this category, and it is entirely avoidable by reading the ring marking.
Crimp, with copper rings to ASTM F1807. The tool squeezes a copper ring until it forms a uniform, donut-shaped indentation around the pipe and fitting. It is permanent, it is what most plumbing inspectors expect to see on PEX-B, and it is verified with a go and no-go gauge. Pro Reddit consensus names it the most fail-safe option behind a wall, which is why it dominates trade work.
Cinch, with stainless steel clamps to ASTM F2098. The tool pinches the clamp flat rather than squeezing a round ring. It is equally permanent and is verified with a different gauge, matched to clamp dimensions. The key rule that causes a large share of returns: an F1807 copper crimper physically cannot close an F2098 stainless clamp, and vice versa. Never mix them.
Expansion, with PEX-A and an expansion fitting. A cold expansion tool stretches the PEX-A pipe over a fitting lip, where it contracts and grips. No ring and no crimp at all, which removes the entire leak category associated with bad crimps. It is the top pick in plumbers’ forums for new construction, and it needs its own tool, never a crimper. We compare the tools in our PEX expansion tool guide.
SharkBite push-to-connect. No tool at all, just a fitting you push the pipe into. It is fast and it dominates forum discussion, but the same forums are full of fittings being returned. Many plumbers will not put them behind drywall for exactly that reason. If you want no risk of a mis-set mechanical connection, crimp or cinch.
Never mix systems. Do not put a crimp-style fitting on PEX-A expansion pipe, and do not fit a copper ring to a stainless clamp tool. The fittings and the tools are standards-matched as a set, and a mismatch is either impossible to close or a joint that will never be correct.
How to Verify a Good Crimp Before You Close the Wall
A PEX joint either holds or it does not, and the only moment you get to find out cheaply is before the drywall goes up. A go and no-go gauge costs almost nothing compared to opening a wall, and it takes seconds per joint. On our jobs it is the step we never skip, and it is the step most often skipped.
How to use it. Slide the ring off and place the correct go side of the gauge over the crimp. It should slide smoothly across the indentation. If it does not fit, or the no-go side will not pass, the crimp is undersized and the joint must be cut out. One joint, one check, no exceptions, no sampling.
Bad crimp signs to look for, all of them visible before the ring goes on the pipe. An uneven crimp where one side of the ring is flattened more than the other means the tool was not square on the ring. A double crimp where the tool was run twice on the same ring produces a thin, split ring. A cracked or visibly deformed ring means the tool exceeded its capacity or the ring was the wrong size. A ring that sits too far from the fitting shoulder leaves the pipe unsupported inside the fitting, and it will weep.
Then pressure test the system. Fill it with water, pressurise to about 1.5 times the working pressure, and leave it there while you walk the entire run and every joint with the water still on. The rule of thumb is that a good joint holds with no visible sign and a bad one shows immediately. Do this before insulation, before wallboard and before you sign off the job.
If a crimp does fail, cut it out rather than trying to add a second ring over the top. A doubled ring on a failed joint hides the problem and puts a crimped-on-crimp stress into the fitting, which is a worse failure than the first one.
How to Choose the Right PEX Crimping Tool
Match the standard before anything else. Read the ring marking on the fittings already in your walls. Copper rings marked to ASTM F1807 need an F1807 crimper, stainless clamps marked ASTM F2098 need an F2098 cinch tool, and PEX-A expansion needs an expansion tool. This single check eliminates most wasted purchases in this category.
Choose your type next. A manual ratchet cinch tool covers most homeowner and remodel work. An angle-head tool is necessary when pipes are already fixed in place, in crawls, between studs and behind fixtures. A cordless electric tool is worth it when you already run that battery platform or expect high volume. A press tool is a different system entirely, covered in our press fitting tool roundup.
Check size coverage against your actual pipe sizes, not the marketing range. Tools that claim 3/8 to one inch frequently ship with rings only in half-inch and three-quarter-inch. Most of the kits here fall into that trap, so treat included rings as a starter supply and order what your layout needs.
Look for a real ratchet. A ratcheting mechanism that will not release until the cycle completes is the single most important quality signal in this category, and it is the difference between a consistent crimp and an optimistic one. A tool that stops anywhere in the stroke is not a crimper, it is a pair of expensive pliers.
Verify the build. Forged steel bodies and Wire EDM cut jaws give repeatable dimensions after thousands of cycles. Plastic handles cut weight and cost you leverage, which is a real trade on larger clamps. Judge build by the jaw, not the handle covering.
Look for a gauge, a calibration path and a warranty. A tool shipped factory adjusted is convenient. A tool that includes a gauge or a calibration tool, or that a manufacturer supports for years, is safer. Repair parts availability matters most of all on a tool you expect to keep for a decade.
Finally, size the tool to your project scale. Under roughly twenty connections, any manual cinch kit is correct and the bundled version is cheapest. Between twenty and two hundred, buy a full-size multi-size tool with an angle head if your runs are confined, plus your own ring supply. Above two hundred connections a day, or for a full repipe, hand fatigue becomes the limiting factor and a cordless or powered tool pays for itself. General hand tools and pipe wrenches are worth having on the same job, and our adjustable wrench set guide covers the fittings work that surrounds every PEX connection.
Frequently Asked Questions
Which PEX crimp method is best?
Copper crimp rings to ASTM F1807 are the most widely accepted method for PEX-B and the easiest to verify with a go/no-go gauge. Stainless steel cinch clamps to ASTM F2098 are equally permanent and the tool is usually lighter to use. PEX-A cold expansion removes rings from the equation entirely and is the preferred method in new construction. For repair work, crimp or cinch on PEX-B is the right answer.
Is it better to crimp or clamp PEX?
Both are permanent, code-accepted connections and both are safe behind a wall when the correct tool is used. Crimp uses a copper ring squeezed to a donut indentation, clamp uses a stainless steel pinch clamp. Choose based on the fittings already in the system, since a copper crimper cannot close a stainless clamp and the standards do not cross over.
Can I use crimp on Expansion PEX?
No. PEX-A expansion pipe uses expansion fittings and a cold expansion tool, and it is crimped only by the tool designed for that system. Mixing a crimp-style fitting onto expansion pipe or using a crimper on an expansion joint produces an incorrect connection. Never mix systems: match the tool to the pipe type and the fitting standard.
Is PEX crimping better than SharkBite?
For permanent, verifiable work behind a finished wall, yes. Crimp connections are permanent, are checked with a go/no-go gauge and are the standard most plumbers and inspectors expect. Push-to-connect fittings require no tool and no verification, and are widely used for repairs and exposed work, but many plumbers avoid them behind drywall because a mis-set connection cannot be seen.
What are the disadvantages of PEX crimping?
The main drawbacks are the tools required, the need to match the ring standard exactly, and the fact that a bad crimp is invisible once the wall is closed. A copper ring tool will not close a stainless clamp, cheap soft-steel tools can be out of tolerance, and hand fatigue sets in on high-volume work. Each of those is avoidable with the right tool and a gauge check on every joint.
How many PEX connections before I need a power crimper?
Around two hundred crimps in a day is the practical threshold. Below roughly twenty connections for a single job, any manual ratchet kit works. Between twenty and two hundred, a full-size multi-size manual tool with a long handle is comfortable. Above two hundred, hand and wrist fatigue becomes the limiting factor and a cordless electric tool earns its cost.
The Verdict: Which PEX Crimping Tool to Buy in 2026
For most people, the best PEX crimping tool for plumbing is the iCrimp cinch and remove kit. It covers 3/8 to one inch stainless clamps, it removes rings as well as closing them, it comes with a cutter and thirty starter rings, and it has the deepest body of owner feedback in the group at more than eight thousand ratings. If your fittings are copper rings rather than stainless clamps, take the multi-size IWISS kit for its interchangeable jaws and one-inch coverage, and the angle-head iCrimp tool when your runs are confined.
Whichever you choose, do three things: read the ring standard before you buy, check every joint with a go and no-go gauge, and pressure test the whole system before it disappears behind a wall. Those three habits prevent more leaks than any brand on this list.
