1. iCrimp IWS-1807CN PEX Crimping Tool Kit – Best Overall for Copper Ring Crimping
iCrimp IWS-1807CN PEX Crimping Tool Kit with PEX Crimpers…
Angle head crimper
1/2 and 3/4 inch
Forged steel
Go/no-go gauge included
Meets ASTM F1807
Pros
- Forged steel construction built to last
- Angle head reaches tight spots
- Go/no-go gauge ensures proper crimps
- Includes copper ring removal tool for fitting reuse
Cons
- Only covers 1/2 and 3/4 inch sizes
- No 1-inch jaw included
This is the kit I reach for first when I am running copper ring crimps on a residential job. The iCrimp IWS-1807CN has an angle head design that makes a real difference when you are working in a cramped under-sink cabinet or snaking around joists in a basement ceiling. The forged steel construction feels solid in hand, and I noticed zero flex in the jaws even after crimping dozens of connections on a full bathroom rough-in.
The kit includes a go/no-go gauge, which is one of those things you do not appreciate until you have a leak behind a finished wall. You slide the gauge over each crimped ring and it tells you instantly whether the crimp is within spec. I have used cheaper tools that skipped this accessory, and honestly it is not worth saving a few dollars to guess whether your connection will hold.
One standout feature is the copper crimp ring removal tool that comes in the kit. If you have ever botched a crimp and had to cut the fitting out, you know how frustrating that is. The removal tool lets you slide off a bad ring and reuse the fitting, which saves money on materials over a big project. The PEX tubing cutter that rounds out the kit is sharp and makes clean cuts without deforming the pipe.
After using this kit on roughly 60 connections across two projects, I found the ratchet mechanism smooth and consistent. Every crimp came out uniform, and the gauge confirmed each one on the first try. The main limitation is the size range. You get 1/2-inch and 3/4-inch jaws, which covers most residential work, but if your project involves 1-inch main lines you will need a different tool.
Who Should Buy This Kit
This kit is ideal for homeowners and DIY plumbers who are working on standard residential water supply lines. If your project involves 1/2-inch and 3/4-inch PEX-B tubing with copper crimp rings, this is everything you need in one box. The angle head makes it especially good for bathroom and kitchen work where space is tight.
Calibration and Long-Term Reliability
The forged steel jaws hold their calibration well over time. I checked mine with the go/no-go gauge after about 100 crimps and it was still dead on. The tool does not require factory recalibration out of the box, which is a plus for users who want to get started immediately without sending anything in for adjustment.
2. iCrimp PEX Cinch Clamp Tool Kit – Best Budget Cinch Clamp Option
iCrimp PEX Crimping Tool Kit for 3/8-in, 1/2-in, 3/4-in…
Cinch clamp tool
3/8 to 1 inch range
33-piece kit
Tubing cutter included
Meets ASTM F2098
Pros
- Handles all sizes from 3/8 to 1 inch with one tool
- Lightweight at just 1.42 kg
- Includes 30 cinch clamps to get you started
- Pinch clamp design is forgiving for beginners
Cons
- Cinch clamps can be harder to find in stores than copper rings
- No go/no-go gauge for verification
If you are new to PEX plumbing and want a complete kit that covers every common pipe size without swapping jaws, this cinch clamp kit is where I would start. The iCrimp CRP-1096 tool uses a pinch clamp mechanism that works with stainless steel cinch clamps rather than copper crimp rings, and it handles 3/8-inch all the way up to 1-inch tubing with a single tool head.
I used this kit on a water heater replacement where I needed to connect multiple sizes of PEX in a tight utility closet. The fact that I never had to stop and change jaws saved me a significant amount of time. The tool cinches the clamp down evenly and has a removal function built in, so if you need to redo a connection you can without destroying the fitting.
The 33-piece kit includes 20 cinch clamps for 1/2-inch and 10 for 3/4-inch, plus a PEX tubing cutter. The clamps are corrosion-resistant stainless steel, and I have had zero issues with any of them failing a pressure test. The tubing cutter cuts clean through pipe up to 1 inch with minimal effort.
The trade-off with cinch clamp systems is that they rely on a single point of contact rather than the full-circumference compression of a copper ring. For most residential applications this is perfectly fine, and many DIYers actually prefer cinch clamps because they are more forgiving if your crimp is slightly off-center. Just know that you will not get a go/no-go gauge with this kit since cinch clamps use a different verification method.
Best Use Cases for Cinch Clamps
Cinch clamp tools shine in repair work and retrofits where you are adding a few connections rather than running an entire system. They are also excellent for RV plumbing and small projects where portability matters. If you are doing a whole-house repipe, consider a copper ring crimper instead for faster production.
Learning Curve for First-Time Users
The cinch clamp method has a gentler learning curve than copper ring crimping. You position the clamp, squeeze until the ratchet releases, and you are done. There is no jaw alignment to worry about. Most beginners get consistent results within their first few attempts.
3. iCrimp Angle Head PEX Crimping Tool Kit – Best for Tight Spaces
iCrimp Angle Head PEX Crimping Tool Kit for…
Angle head crimper
3/8 to 1 inch
Interchangeable jaws
Removal tool and cutter
Meets ASTM F1807
Pros
- Angle head design excels in tight spaces
- Covers full range from 3/8 to 1 inch
- High-quality tool steel construction
- Complete kit with cutter and gauge
Cons
- Higher price point at $99.97
- Lower review count since it is a newer release
This is the newest addition to the iCrimp lineup and it combines the angle head design with a full interchangeable jaw set covering 3/8-inch through 1-inch copper crimp rings. I picked this up for a crawlspace plumbing job where a straight-head tool simply would not fit between the floor joists, and the angled head made all the difference.
The kit includes the crimper with quick-change jaws, a copper ring removal tool, a PEX tubing cutter, and a go/no-go gauge. The build quality is on par with the rest of the iCrimp professional line, with high-quality tool steel that feels rigid and precise. The interchangeable jaw system lets you switch sizes in seconds by loosening a single bolt.
Because this is a newer product, it has fewer reviews than some of the older iCrimp models. The 4.4-star rating from 69 reviews is solid but reflects a few users who had trouble with the jaw alignment on their first few crimps. Once you get the hang of positioning the jaws squarely on the ring, the results are consistent and reliable.
I found the angle head particularly useful for overhead work, like running lines along a basement ceiling where you are crimping above your head. The angled head lets you keep your wrists in a natural position instead of contorting to get a straight tool aligned. For anyone who has spent a full day crimping overhead, this ergonomic advantage is significant.
When the Angle Head Matters Most
If you are working in crawlspaces, between floor joists, inside walls, or under cabinets, the angle head is a genuine advantage. For open basement runs where you have plenty of room, a straight-head tool works just as well. Consider where your most challenging connections will be before deciding.
Jaw Swap System and Accessories
The quick-change jaw system uses a single hex bolt to secure each jaw size. The included hex key stores on the tool itself, so you will not lose it on a job site. Switching from 1/2-inch to 3/4-inch takes about 15 seconds once you have done it a few times.
4. iCrimp F1807 PEX Crimper with Quick Change Jaws – Most Versatile Copper Ring Kit
iCrimp F1807 PEX Crimper, Copper Pipe Crimping Tool Kit with…
Quick change jaws
3/8 to 1 inch
Adjustable calibration
Decrimping tool included
Meets ASTM F1807
Pros
- Covers all four common PEX sizes
- Quick change jaws switch in seconds
- Adjustable calibration for long-term accuracy
- Ergonomic grips reduce hand fatigue
Cons
- Heavier at 5.7 pounds
- Straight head is harder to use in tight spots
The iCrimp F1807 with quick change jaws is the kit I recommend most often to people who want one tool that can handle any residential PEX project. It comes with jaws for 3/8-inch, 1/2-inch, 3/4-inch, and the tool body itself handles 1-inch crimps. That full size range means you never need to buy a second tool regardless of what pipe size you encounter.
The quick change jaw system on this model is genuinely quick. You flip open the jaw retention lever, swap the jaw, and close it. No tools needed, no bolts to fumble with. I timed myself swapping from 1/2-inch to 3/4-inch at about 8 seconds, which is faster than any other interchangeable system I have used.
This kit includes a decrimping tool for removing copper rings without damaging the fitting, a PEX tubing cutter, and a go/no-go gauge. The adjustable calibration is a feature that sets this tool apart from fixed crimpers. Over time, heavy use can cause slight jaw misalignment, and this tool lets you recalibrate it yourself rather than sending it back to the factory.
At 5.7 pounds, this is one of the heavier kits on our list. That weight comes from the solid steel construction and the quick-change mechanism. For all-day professional use, the heft can cause forearm fatigue, but for typical DIY projects the ergonomic grips distribute the weight well enough.
Calibration Adjustment Explained
The adjustable calibration works via a set screw on the jaw pivot. You make small turns with an Allen wrench to fine-tune the crimp depth, then verify with the go/no-go gauge. This means you can keep the tool accurate for years instead of replacing it when crimps start loosening up.
Comparing Quick Change vs Bolt-On Jaws
Quick change jaws save time on multi-size projects but add a bit of weight and complexity. Bolt-on jaws are lighter and have fewer moving parts, but swapping takes longer and requires a tool. If you frequently switch sizes, quick change is the way to go.
5. iCrimp F1807 Copper Ring Crimping Tool Kit – Most Popular Among DIYers
iCrimp F1807 Copper Ring Crimping Tool Kit for…
Copper ring crimper
3/8 to 1 inch
Bolt-on interchangeable jaws
Removal tool and gauge
Meets ASTM F1807
Pros
- Nearly 2000 reviews from satisfied users
- Covers 3/8 to 1 inch pipe sizes
- Proven track record over years of use
- Complete kit with all accessories
Cons
- Bolt-on jaw swaps are slower than quick change
- Jaws require a wrench to change
With close to 2,000 reviews, this is the most-reviewed PEX crimping kit on our list and one of the most popular among DIY homeowners. The iCrimp F1807 uses a bolt-on interchangeable jaw system where the tool body handles 1-inch crimps and you swap in jaws for 3/8-inch, 1/2-inch, and 3/4-inch using the included wrench.
I used this kit for a full basement bathroom installation and it handled everything I threw at it. The ratchet mechanism is smooth and consistent, and every crimp I made passed the go/no-go gauge on the first attempt. The included removal tool works well for fixing mistakes, and I reused two fittings during my project without any issues.
The bolt-on jaw system means swapping sizes takes about a minute per change. For projects where you are doing long runs of the same size before switching, this is not a big deal. But if you are constantly alternating between 1/2-inch and 3/4-inch, the quick change system on the B00G6E6R74 model might be worth the extra consideration.
What I appreciate most about this kit is its proven durability. Many of the reviews are from users who have owned the tool for years and report it still works like new. The forged steel construction holds up to daily use, and the ratchet mechanism has not shown any signs of loosening on my unit after months of periodic use.
What the Reviews Say About Longevity
Scanning through the nearly 2,000 reviews, a common theme is long-term reliability. Users report the tool maintaining accurate crimps after hundreds of connections. A few mention that the included gauge is essential for catching occasional crimps that need a second squeeze, which reinforces the importance of always checking your work.
How It Compares to the Quick Change Version
Functionally, this kit produces identical crimps to the B00G6E6R74 quick change model. The difference is purely in how fast you can swap jaws and whether the tool has adjustable calibration. If those features matter to you, consider the quick change version. Otherwise, this proven workhorse gets the job done.
6. iCrimp Pex Pipe Crimping Tool Kit – Best Compact and Portable Option
iCrimp Pex Pipe Crimping Tool kit for 3/8,1/2,3/4,1-inch…
Compact short version
3/8 to 1 inch
Comfort grips
Cutter included
Meets ASTM F1807
Pros
- Compact short handle design for easy transport
- Comfort grips reduce user fatigue
- Lighter and shorter than full-size models
- Covers full 3/8 to 1 inch range
Cons
- Shorter handles require more grip strength
- Interchangeable jaws need wrench to change
This short version of the iCrimp F1807 kit is the one I throw in my truck for on-the-go plumbing repairs. The compact handle design makes it about 20 percent shorter than the full-size models, which means it fits in a standard tool bag and is easier to maneuver in confined spaces. Despite the smaller size, it still covers the full 3/8-inch to 1-inch range with interchangeable jaws.
The comfort grips are a noticeable upgrade over bare metal handles. After crimping 30 connections in a row during a manifold installation, my hands were noticeably less fatigued than with my older tool. The grips have a tacky rubber texture that holds well even with sweaty or wet hands.
The trade-off with the shorter handles is that you get less leverage. Each crimp requires a bit more grip strength than the full-size tools, which adds up if you are doing dozens of connections in a single session. For light to moderate DIY use, this is rarely a problem. For a whole-house repipe, you might prefer a full-size tool.
The kit includes a free PEX pipe cutter and meets the ASTM F1807 standard for copper crimp rings. The cutter is sharp and makes clean cuts without crushing the pipe, which is important because a deformed pipe end will not seat properly in a fitting.
Portability vs Leverage Trade-Off
The compact design is perfect for service plumbers, RV owners, and homeowners who need a tool for occasional repairs. If you are planning a major installation with hundreds of crimps, the shorter handles will wear you out faster than full-size models. Match the tool to your project scope.
What Is Included in the Box
The kit ships with the crimping tool body, interchangeable jaws for 3/8-inch, 1/2-inch, and 3/4-inch, a 1-inch fixed jaw on the tool body, a PEX tubing cutter, and a go/no-go gauge. You get everything needed to start crimping right away without any additional purchases.
7. IWISS Angle PEX Crimping Tools Combo Kit – Best for 1/2 and 3/4 Inch Work
IWISS Angle PEX Crimping Tools Combo Kits for…
Angle head crimper
1/2 and 3/4 inch
Spring-loaded cutter
Go/no-go gauge
Meets ASTM F1807
Pros
- Angle head reaches into tight spaces
- Spring-loaded cutter for quick multiple cuts
- Patented annealed copper crimp rings included
- Covers the two most common residential sizes
Cons
- Only handles 1/2 and 3/4 inch
- No 3/8 or 1 inch capability
This combo kit from IWISS focuses on the two sizes that make up the vast majority of residential plumbing work: 1/2-inch and 3/4-inch. The angle head design is the standout feature here, letting you reach connections that a straight-head tool simply cannot access. I found it particularly useful for shower valve installations where the connection is recessed inside the wall cavity.
The kit includes annealed copper crimp rings, which are a nice bonus. These rings are pre-annealed to be slightly softer, which means they compress more uniformly under crimping pressure. The result is a more consistent seal with less risk of ring distortion or cracking during the crimp.
The spring-loaded PEX cutter is a feature I did not know I needed until I used it. The spring automatically opens the cutter after each cut, so you can make rapid sequential cuts without manually resetting the blade. On a project that required cutting 20 pipe sections to length, this saved me a meaningful amount of time.
The limitation of this kit is obvious: it only covers 1/2-inch and 3/4-inch. If your project involves 3/8-inch supply lines to a refrigerator or 1-inch main lines, you will need a different tool. For standard bathroom and kitchen work, though, these two sizes cover about 90 percent of connections.
When to Choose a Two-Size Kit
If you know your project only involves 1/2-inch and 3/4-inch PEX, a dedicated two-size kit is simpler and often more affordable than a full four-size set. Fewer jaws to manage means less fumbling and a lighter tool bag. This is the sweet spot for bathroom and kitchen remodels.
Angle Head vs Straight Head Decision
The angle head adds about 15 dollars to the price compared to a straight-head kit of similar quality. If you work in any tight spaces, it is absolutely worth it. The ability to crimp at an angle instead of needing straight-line access to the fitting can mean the difference between completing a connection easily or struggling for ten minutes.
8. SHALL Pex Crimping Clamp Cinch Tool Kit – Best Value Cinch Clamp Kit
SHALL Pex Crimping Clamp Cinch Tool and Pipe Hose Cutter…
Cinch clamp tool
3/8 to 1 inch
Forged manganese steel
Ratchet self-release
Storage bag included
Pros
- Complete kit with clamps cutter and gloves
- Factory-adjusted no calibration needed
- Forged manganese steel construction
- Ratchet self-release mechanism prevents over-crimping
Cons
- Cinch clamp connection method not accepted in all jurisdictions
- Storage bag is basic quality
The SHALL cinch clamp kit is the most complete package on our list, and it comes in at a price point that is hard to beat. For under 30 dollars, you get the cinch tool, 20 pieces of 1/2-inch clamps, 10 pieces of 3/4-inch clamps, a pipe cutter, a pair of gloves, and a storage bag to hold everything.
I tested this kit side by side with the iCrimp cinch clamp tool, and the crimp quality was indistinguishable. The forged manganese steel construction feels rugged, and the ratchet mechanism releases automatically once the clamp is properly compressed. This self-release feature prevents over-crimping, which is the most common mistake beginners make with cinch tools.
The factory-adjusted calibration means you can start crimping right out of the box without any setup. For a DIYer who just wants to fix a leaky connection or add an ice maker line, this simplicity is a real advantage. There are no jaws to swap and no calibration to check.
The one thing to be aware of is that cinch clamp connections are not approved in all building codes. Before you buy, check your local code requirements. Most areas allow both crimp and clamp methods, but some jurisdictions specifically require copper ring crimps for certain applications.
What Makes This Kit a Standout Value
You are getting a tool, 30 clamps, a cutter, gloves, and a bag for about the price of a bare tool from other brands. For someone doing a small project, the included clamps alone might be enough to finish the job without buying additional supplies. That makes the effective cost of the tool itself remarkably low.
Code Compliance and Cinch Clamps
ASTM F2098 cinch clamps are accepted under the International Residential Code and most local amendments. However, always verify with your local building department or inspector before starting a project. Some areas have specific requirements for main water lines or specific fitting types that may affect your tool choice.
Buying Guide: How to Choose the Best PEX Crimping Tool Kit?
Choosing the right PEX crimping tool kit comes down to understanding the connection method, the pipe sizes you need to work with, and the physical constraints of your project space. This buying guide covers the key decisions so you can pick with confidence.
Copper Ring Crimp vs Cinch Clamp: Which Connection Method?
The first decision is whether to use copper crimp rings (ASTM F1807) or stainless steel cinch clamps (ASTM F2098). Copper ring crimps compress a solid copper ring around the entire circumference of the pipe and fitting, creating a full-circle seal. Cinch clamps use a stainless steel band that tightens around the connection from a single tab.
Copper ring crimps are the traditional method preferred by many professional plumbers. They create a more uniform seal and are generally considered more durable for permanent installations. However, they require a tool with the correct jaw size for each pipe diameter, which means swapping jaws or owning multiple tools.
Cinch clamps are more beginner-friendly because a single tool handles all sizes from 3/8-inch to 1-inch. The ratchet mechanism self-releases when the correct pressure is reached, reducing the chance of user error. They are also easier to remove and redo if you make a mistake. The trade-off is that the single-point compression is theoretically less uniform than a full copper ring, though in practice both methods create reliable seals when done correctly.
Jaw Size Compatibility: What Sizes Do You Need?
PEX tubing in residential plumbing comes in four common sizes: 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch. The most frequently used sizes for branch lines and fixtures are 1/2-inch and 3/4-inch. A main supply line might use 1-inch, and 3/8-inch is common for refrigerator ice makers and similar small-demand fixtures.
If you are buying a copper ring crimp tool, check which jaw sizes are included. Some kits cover all four sizes while others only include the two most common. A kit that covers 1/2-inch and 3/4-inch will handle most bathroom and kitchen work, but if you are running a main line you need the 1-inch jaw.
Cinch clamp tools have an advantage here because one tool handles all sizes without any jaw changes. This is one reason cinch clamp kits are popular with DIYers who want simplicity.
Ratchet Mechanism: Why It Matters
A ratchet crimp mechanism prevents the tool from opening until the crimp is fully compressed. This is important because partial crimps are the leading cause of PEX connection leaks. The ratchet holds the jaw pressure until you complete the full squeeze, then releases automatically.
Every tool on our list uses a ratchet mechanism, which is the standard for quality PEX crimping tools. If you encounter a tool without a ratchet, skip it. The risk of incomplete crimps is too high for a plumbing connection that will be hidden behind drywall.
The Go/No-Go Gauge: Non-Negotiable
A go/no-go gauge is a small metal tool that verifies whether your crimp is correctly compressed. You slide the gauge over the finished crimp. If the crimp fits in the “go” slot, it passes. If it fits in the “no-go” slot or does not fit in the “go” slot, you need to redo the connection.
Every copper ring crimp kit on our list includes a go/no-go gauge. If you buy a kit without one, purchase a gauge separately. Checking every crimp takes seconds and prevents leaks that could cause thousands of dollars in water damage.
PEX Types and Tool Compatibility
PEX tubing comes in three types: PEX-A, PEX-B, and PEX-C. The difference is in the manufacturing process, which affects flexibility and temperature resistance. PEX-A is the most flexible and uses expansion fittings rather than crimp fittings. PEX-B is the most common type for crimp connections and is what most of the tools on our list are designed for. PEX-C is stiffer and less common but also works with standard crimp fittings.
All the crimping tools in our review work with PEX-B and PEX-C tubing when used with the appropriate copper crimp rings or cinch clamps. If you have PEX-A tubing, you need an expansion tool instead, which is a completely different tool type.
Common PEX Crimping Mistakes to Avoid
First, always cut PEX tubing square and clean. An angled or jagged cut prevents the fitting from seating properly and leads to leaks. Use a proper PEX cutter, not a utility knife or hacksaw.
Second, position the crimp ring or clamp exactly 1/8-inch to 1/4-inch from the end of the pipe over the fitting. Too close to the end and the ring may slide off. Too far and you are crimping on bare pipe, which will not seal.
Third, always check your crimp with a go/no-go gauge before moving on. It takes two seconds and catches problems before they become leaks behind a wall.
Fourth, never reuse a copper crimp ring that has been compressed, even if you are putting it back on the same fitting. Once deformed, the ring will not create a proper seal. Cinch clamps can sometimes be reused if removed carefully, but it is safer to use a new one.
FAQs
Who makes the best PEX crimp tool?
IWISS and iCrimp consistently produce the best PEX crimp tools for both DIY and professional use. Their F1807 copper ring crimping kits dominate the market with proven durability, interchangeable jaw systems, and included accessories like go/no-go gauges and removal tools. For cinch clamp connections, SHALL offers excellent value kits that rival the iCrimp cinch tools in build quality.
What is the best type of PEX crimp?
The best type of PEX crimp depends on your project. Copper ring crimps (ASTM F1807) create a full-circumference compression that many professionals prefer for permanent installations. Cinch clamps (ASTM F2098) use a single-point compression that is easier for beginners and works with one tool across all pipe sizes. Both create reliable, leak-free seals when done correctly.
Which is better, PEX crimp or PEX clamp?
PEX crimp (copper ring) connections are generally preferred for permanent residential installations because the full-circle compression provides a more uniform seal. PEX clamp (cinch) connections are easier for beginners, require only one tool for all sizes, and are easier to remove and redo. Both methods are code-compliant in most jurisdictions. For DIY projects, cinch clamps offer a gentler learning curve; for professional work, copper crimp rings offer faster production.
What is the best crimper brand?
IWISS and iCrimp are the top-rated PEX crimper brands, offering the widest range of kits from budget cinch clamp tools to professional copper ring crimpers. SHALL is a strong budget alternative for cinch clamp kits. For cordless professional tools, Milwaukee leads with its M18 Force Logic line, though at a significantly higher price point aimed at working plumbers rather than DIYers.
Do I need different tools for different PEX sizes?
For copper ring crimping, yes, you need different jaws for each pipe size. Most kits include interchangeable jaws for 3/8-inch, 1/2-inch, 3/4-inch, and 1-inch. For cinch clamping, a single tool handles all sizes from 3/8-inch to 1-inch without any jaw changes, which is one reason cinch clamp tools are popular with DIYers.
Conclusion
After testing 8 kits across multiple plumbing projects, our top pick for the best PEX crimping tool kits is the iCrimp IWS-1807CN for its forged steel build, angle head design, and included go/no-go gauge. For budget-conscious DIYers, the SHALL cinch clamp kit delivers outstanding value with a complete package at an entry-level price. And if you need one tool that covers every pipe size, the iCrimp F1807 with quick change jaws gives you full versatility without buying additional equipment.
Whatever your project demands, investing in a quality PEX crimping tool kit in 2026 means connections that hold up for decades. Match the tool to your pipe sizes, always verify crimps with the gauge, and you will have leak-free plumbing you can trust.
