For flexible PEX plumbing, the right crimping tool depends on whether your pipe connections use stainless steel cinch clamps or copper crimp rings. The iCrimp 33-piece kit is best for a ready-to-use cinch setup with included clamps, while the SHALL kit suits buyers who want a ratcheting, self-releasing tool. For copper rings, choose the IWISS/iCrimp F1807 kit. The products below are designed for PEX connections; check your fitting and ring or clamp type before buying because cinch and copper-ring tools are not interchangeable.
| Product | Connection type | Best for |
|---|---|---|
| iCrimp 33-Piece Kit | Stainless steel cinch clamps | Complete starter set |
| SHALL Cinch Tool Kit | Stainless steel clamps | Ratchet operation |
| IWISS Copper Ring Kit | Copper crimp rings | Multiple pipe sizes |
| OURU Cinch and Remove Kit | Stainless steel clamps | Storage and removal function |
| iCrimp Universal Cinch Tool | Stainless steel clamps | Tool-only flexibility |
iCrimp 33-Piece PEX Cinch Kit
This kit is best for homeowners or plumbing workers who want the cinch tool, removal function, cutter, clamps, and carrying case together. Its listed clamp sizes range from 3/8 inch to 1 inch, and the included stainless steel rings are 1/2 inch and 3/4 inch. The tool can cinch clamps and remove them so fittings can be reused.
Choose this kit if you need several cinch sizes and want included consumables. It is specified for stainless steel clamp rings used with brass or poly PEX fittings. The included clamps cover only 1/2-inch and 3/4-inch sizes, so other sizes may need to be purchased separately.
SHALL Ratcheting PEX Cinch Tool Kit
The SHALL kit is best for buyers who prefer a ratchet and self-releasing mechanism. The product information says it works with 3/8-inch to 1-inch stainless steel clamps from different manufacturers and meets ASTM F2098. It is also described as suitable for some single-ear hose clamps when the clamp ear fits within the jaw opening.
The kit includes a pipe cutter, storage bag, 20 half-inch clamps, and 10 three-quarter-inch clamps. Its forged manganese-steel body and wire-EDM-cut jaw are listed as durability and precision features. Avoid choosing it for copper crimp rings; it is a cinch-clamp tool.
IWISS iCrimp Copper Ring Tool Kit
This kit is best for PEX installations that use copper crimp rings rather than stainless steel cinch clamps. It is specified to meet ASTM F1807 and to connect PEX pipe to brass or poly fittings using copper rings. The listing describes the tool as smaller and lighter while providing the required pressure.
Choose this option when your fittings and rings match the copper-ring system. Its key limitation is that the supplied information does not describe cinching or clamp removal; it should not be treated as a universal cinch tool. Confirm that the pipe size and ring dimensions match the tool before starting the job.
OURU Cinch and Removal Kit With Box
The OURU kit is best for buyers who want a portable set with clamp removal and a storage box. It includes a PEX cinch-and-removal tool, a cutter, 25 half-inch clamps, and 10 three-quarter-inch clamps. The tool is made from manganese steel and has a non-slip grip, according to the product details.
Its removal function is intended to take clamps off while protecting the pipe. Choose it for jobs centered on the two included clamp sizes. The supplied clamp selection does not cover every size the tool may accommodate, so check what your project requires before purchase.
iCrimp Universal Stainless Clamp Tool
This tool is best for buyers who already have compatible clamps and want a cinching tool without a larger bundled kit. It is listed for stainless steel clamps from 3/8 inch to 1 inch and meets ASTM 2098, as stated by the product listing. It can also work with some single-ear hose clamps if the ear fits the jaws.
The forged steel construction and wire-EDM-cut jaw are listed features. Since this option is presented as a tool rather than a full bundle, do not assume it includes clamps, a cutter, or a case. Check the package contents and your clamp style before ordering.
Buying Guide: How To Choose A PEX Crimping Tool
Do you need a cinch tool or a copper-ring crimper?
Start by identifying the connection hardware specified for your PEX fittings. Cinch tools compress stainless steel clamps around compatible fittings. Copper-ring crimpers are designed for copper rings. These systems use different tools, so buying by the general phrase “flex pipe crimping tool” alone can lead to a mismatch.
Which pipe and clamp sizes do you need?
Match the tool’s stated size range to the pipe and clamp sizes in your project. A tool may cover several sizes while a kit includes clamps for only some of them. Compare the included clamp sizes with your parts list, and confirm that the fittings and rings or clamps are intended to work together.
Is clamp removal important?
A removal function can be useful when reworking a connection or reusing a fitting, as described for several cinch kits above. It does not make a cinch tool compatible with copper rings. If removal matters, verify that the specific model explicitly lists that function.
What should you check before crimping?
- Confirm the fitting system, clamp or ring type, and tool type match.
- Check the tool’s size range and the sizes included in the package.
- Follow the tool and fitting manufacturers’ installation instructions.
- Use a suitable cutter to make a clean, square pipe end when required.
Frequently Asked Questions
Can one PEX tool crimp both copper rings and stainless clamps?
Not necessarily. Cinch tools and copper-ring crimpers use different mechanisms. Select the tool that matches the connection hardware.
Is a PEX cinch tool the same as a flex pipe crimping tool?
“Flex pipe crimping tool” can refer to different tools. The products in this guide are for PEX connections, particularly stainless steel cinch clamps or copper crimp rings.
Do these kits include clamps?
Some do and some may be tool-focused. Check each product’s listed contents; the iCrimp 33-piece and SHALL kits, for example, list included clamps.
Can a cinch tool remove clamps?
Some models explicitly include clamp removal, including several kits in this guide. Confirm the feature for the exact tool you select.
Why should I check the standard listed for a tool?
A stated standard can help you compare the tool with the connection system it is designed for. Verify the requirements for your fittings and follow the manufacturer’s installation instructions.
