Our Picks: Best Pex Crimping Tools For Home Plumbing reviews
1. iCrimp Cinch and Removal Tool Kit: A versatile clamp-system starter set
This kit is for PEX connections made with stainless steel cinch clamps, not copper crimp rings. Its combination tool can tighten clamps and remove them, which can help when you need to take apart a connection and reuse a fitting. The listed working range is 3/8 to 1 inch.
The ratcheting design has a self-release mechanism, and the tool is factory-adjusted according to the product details. The set also includes a PEX cutter, 20 half-inch clamps, and 10 three-quarter-inch clamps. That gives you basic supplies for common home plumbing sizes, though you may need to buy other clamp sizes separately.
Its main advantage over a basic cinch tool is the built-in removal function. The tool is described as meeting ASTM F2098, and the manufacturer says it works with stainless steel clamps from any manufacturer. Before starting a job, still confirm that the clamp and fitting system you have is suitable for the tool and your installation.
Pros:
- Cinches and removes stainless steel clamps with one tool.
- Works across a stated 3/8-to-1-inch range.
- Includes a cutter and two common clamp sizes.
- Factory-adjusted, with no calibration tool required according to the product details.
Cons:
- Designed for clamp connections, not copper crimp rings.
- The included clamps cover only two sizes.
Verdict: Choose this kit if your plumbing uses stainless steel cinch clamps and you want one tool for installation and removal.
2. iCrimp Clamp Tool Kit with Case: Broad size coverage in a portable set
This iCrimp set is another option for stainless steel clamp connections. It covers 3/8, 1/2, 5/8, 3/4, and 1-inch clamp sizes, giving it an extra listed size compared with several other kits here. The tool combines cinching and clamp removal, so it can serve for both new connections and some repair work.
The kit comes in a carrying case and includes a cutter, 20 half-inch clamps, and 10 three-quarter-inch clamps. Its product information says it meets ASTM F2098 and is NSF certified. It is also described as suitable for brass or poly PEX barb fittings. The clamp assortment is useful for common sizes, but it does not provide clamps for every size the tool can handle.
Compared with the first iCrimp clamp kit, this one clearly lists five clamp sizes and adds a case. It may suit homeowners who want the flexibility to work with more tubing sizes while keeping the tools together. As with any clamp system, make sure your clamps, fittings, and tool are compatible before making a connection.
Pros:
- Lists compatibility with five clamp sizes from 3/8 to 1 inch.
- Combines clamp cinching and removal.
- Includes a carrying case, cutter, and clamps in two sizes.
- Product details state that it meets ASTM F2098 and is NSF certified.
Cons:
- Included clamps do not cover all five listed tool sizes.
- Not intended for copper-ring crimp connections.
Verdict: This is a good fit if you want a case and broader clamp-size coverage for a range of home plumbing tasks.
3. IWISS Copper Ring Crimp Kit: A straightforward choice for copper rings
Unlike the clamp kits above, this set is made for copper crimp rings used with brass or poly PEX fittings. It includes a one-inch crimper and interchangeable jaws for 3/8-, 1/2-, and 3/4-inch rings. The product details say the tool meets ASTM F1807.
A go/no-go gauge is included to check completed crimps, along with a cutter and spanner. The gauge is a useful addition for homeowners who want to check their work rather than relying on feel alone. The set is described as smaller and lighter while still providing the required crimp pressure, and its comfort grips are intended to help reduce hand fatigue.
This is the more focused choice for someone who already uses copper crimp rings or is building a system around them. It does not list a clamp-cinching function or a ring-removal tool, and the supplied information does not list any rings in the kit. Plan on sourcing compatible rings and fittings separately.
Pros:
- Works with copper crimp rings in four listed sizes.
- Includes a go/no-go gauge, cutter, and spanner.
- Product details state that it meets ASTM F1807.
- Comfort grips and a lighter design are intended to make handling easier.
Cons:
- Does not include a stated ring-removal tool.
- Rings are not listed among the included items.
Verdict: Pick this kit if you need a multi-size copper-ring crimper and want a gauge for checking your crimps.
4. iCrimp Angle-Head Copper Crimp Kit: A practical option for tight spaces
This compact kit is designed for copper crimp rings in 1/2- and 3/4-inch sizes. Its angle-head crimpers are intended to make access easier in confined areas, such as around existing plumbing. The tools are described as factory calibrated, and a go/no-go gauge is included for checking crimps.
The five-piece set also includes a cutter and a copper ring removal tool. The removal tool handles 1/2-, 3/4-, and 1-inch rings, so its removal range is wider than the crimpers’ stated size range. The kit comes in a carrying case, and its forged-steel construction is intended for a secure connection and long service life.
Compared with the broader IWISS crimper above, this set has fewer crimp sizes but adds ring removal and an angled head. It may be more useful for repairs or remodeling where access is limited and you need to remove an old copper ring. It is not a stainless steel clamp tool, so it is not the right match for a cinch-clamp system.
Pros:
- Angle-head crimpers are suited to confined spaces.
- Includes a gauge, cutter, copper ring removal tool, and case.
- Crimpers are factory calibrated according to the product details.
- Removal tool works with three copper ring sizes.
Cons:
- Crimping is limited to 1/2- and 3/4-inch rings.
- Not designed for stainless steel cinch clamps.
Verdict: Choose this kit for copper-ring work in tight spots, especially if you also need a removal tool for repairs.
5. OURU Cinch and Removal Tool Kit: A clamp-system set with a storage box
The OURU kit is built around stainless steel PEX clamps and a tool that can cinch or remove them. Its listed working range is 3/8 to 1 inch. The set includes a PEX cutter, a storage box, 25 half-inch clamps, and 10 three-quarter-inch clamps.
The tool uses a ratcheting design with a self-release mechanism, and the product description says switching between cinching and removal takes only a few seconds. Its body is described as manganese steel with non-slip grips. These features may be useful if you have several connections to make, though the clamp assortment is limited to two sizes.
It has a similar purpose to the iCrimp clamp kits: both combine installation and removal in one tool. The main differences here are the stated clamp quantities and the included storage box. The product details do not list a specific ASTM standard or certification, so check the tool and clamp requirements for your project before buying.
Pros:
- Cinches and removes stainless steel clamps.
- Listed for clamp sizes from 3/8 to 1 inch.
- Includes a cutter, storage box, and clamps in two common sizes.
- Ratcheting and self-release features are designed to simplify operation.
Cons:
- The included clamps do not cover the full listed tool range.
- The supplied product details do not state a standard or certification.
Verdict: Consider this kit if you want a clamp tool, removal function, and storage box, and have confirmed it suits your plumbing system.
How to Choose a PEX Crimping Tool for Home Plumbing
Match the tool to your connection method
First find out whether your PEX system uses copper crimp rings or stainless steel cinch clamps. A copper-ring crimper is made to compress copper rings around compatible fittings. A cinch tool tightens stainless steel clamps. These are different connection methods, so buying a tool for one does not mean it will work with the other. Check the fittings and rings or clamps you plan to use before choosing.
Check the sizes you need
Look at the pipe sizes in your project and compare them with the tool’s stated range. A kit may handle several sizes but include clamps or jaws for only some of them. For example, some clamp kits in this guide work across a broad range but include only half-inch and three-quarter-inch clamps. Confirm both the tool’s capacity and the supplies in the box.
Consider the standard and inspection tools
For copper crimp connections, a go/no-go gauge can help you check whether a completed crimp is within the gauge’s limits. Some products also list a standard they meet, such as ASTM F1807 for a copper-ring tool or ASTM F2098 for a clamp tool. Confirm that the product’s stated standard and the connection method match the requirements for your fittings and plumbing job.
Think about access and removal needs
Plumbing work in a cabinet or near other pipes can leave little room to position a tool. An angle-head crimper may be useful in tight areas, while a compact kit can be easier to store between repairs. If you may need to take apart an existing connection, look for a kit that specifically includes the right kind of removal function: clamp removal and copper-ring removal are not the same.
Decide whether a complete kit is worth it
A kit with a cutter, gauge, case, and connection supplies can reduce the number of separate tools you need to buy. But extras are only useful if they match your system. Check what is actually included, especially the sizes and quantities of clamps or rings. If you already own a cutter or only need one specific crimper, a smaller set may make more sense.
Check the connection system and local requirements
Compatibility depends on more than pipe size. Verify that your tool, tubing, fittings, and rings or clamps are designed to work together. Follow the tool instructions and applicable plumbing requirements for your project. If you are unsure about a connection, ask a qualified plumbing professional before putting the line into service.
Frequently Asked Questions
Are PEX crimping tools and cinch tools the same?
No. A crimping tool compresses a copper ring, while a cinch tool tightens a stainless steel clamp. Choose the tool that matches the connection system used by your fittings and pipe.
Can one tool work with every PEX connection?
No single tool should be assumed to work with every system. Check the tool’s listed ring or clamp type, size range, and compatibility information. The products in this guide include separate options for copper rings and stainless steel clamps.
Do I need a gauge for PEX connections?
A go/no-go gauge is useful for checking crimps on systems that call for that inspection method. Two copper-ring kits listed here include a gauge. Follow the tool instructions and the requirements for your specific fittings.
Can a cinch tool remove copper crimp rings?
Do not assume it can. Clamp removal and copper-ring removal are different functions. Check the kit description for the specific removal tool and connection type it supports.
Which kit is better for a tight plumbing space?
The iCrimp angle-head copper crimp kit is specifically described as suited to confined spaces. It crimps 1/2- and 3/4-inch copper rings. For a clamp system, choose a compatible clamp tool and consider how much room you have to position its jaws.
Do these kits include all the rings or clamps I might need?
No. The clamp kits listed here include clamps in half-inch and three-quarter-inch sizes, while their tools may cover a wider range. The copper-ring kit descriptions do not list rings as included. Check the kit contents and buy compatible supplies in the sizes your project requires.
Final Recommendation
For a stainless steel clamp system, the iCrimp clamp kit with a case is a flexible starting point because it lists five supported sizes and includes a cutter and clamps. For copper-ring connections, the IWISS kit offers four crimp sizes and a gauge, while the iCrimp angle-head set is a better fit when access is tight or ring removal matters. The best choice is the one that matches your existing fittings, connection method, and pipe sizes.
