IWISS Angle PEX Crimping Tools Combo Kit for 1/2 in & 3/4 in - Compact

Our review of the IWISS Angle PEX Crimping Tools Combo Kit finds it most useful for DIY plumbers and tradespeople who need a compact, all-in-one solution for PEX copper crimp ring installations. The bottom line: this kit combines a dual-cavity angle-head crimper, a spring-loaded shear cutter, and a supply of annealed copper crimp rings so users can complete 1/2 in and 3/4 in F1807 style crimps without running between tools. The one-handed crimp design and angle head make overhead and tight-space work noticeably easier than a straight-head tool.

Key Features

• All-in-one kit: Includes a PEX crimping tool, PEX cutter, twenty 1/2 in rings and ten 3/4 in rings so a single purchase covers common fittings without extra parts.
• Angle head crimper: The angled head design gives better access in confined areas and between joists, reducing awkward hand positioning during crimps.
• Dual cavity crimping: Crimps both 1/2 in and 3/4 in copper crimp rings with a one-handed operation that speeds repeated connections.
• Patented annealed copper rings: The supplied copper rings are annealed for longevity and intended to form reliable seals on F1807 brass and PPSU fittings.
• Shear PEX cutter: The spring-loaded cutter slices PEX tubing cleanly for water applications, making repeat cuts quicker and more accurate.
• F1807 compatibility: Designed to work with crimp style brass and poly fittings made to F1807/F877 or F2159 standards, so it fits many common brands of fittings.

Who It's For

This kit is aimed at homeowners doing PEX plumbing repairs or small installations and contractors who need a compact toolkit for tight spaces. The bundled rings and cutter mean a single bag can handle most 1/2 in and 3/4 in crimp needs on the job, and the angle head is particularly helpful for overhead or between-joist work.

Those who perform heavy daily production crimping or who prefer ratcheting, calibrated crimp tools for high-volume commercial plumbing may want a different pro-grade tool. Also, if you use compression or expansion fittings rather than F1807 crimp fittings, this kit will not replace those specific tools.

Pros & Cons

Pros

• Compact angle-head design improves access in tight spots and overhead locations.
• Complete starter kit includes cutter and a useful quantity of 1/2 in and 3/4 in annealed copper rings.
• Dual cavity crimper supports one-handed crimps for both common PEX ring sizes, saving time on small jobs.
• Cutting tool is spring-loaded and makes fast, clean cuts in PEX tubing.

Cons

• Some users may find it requires significant hand force to achieve a full crimp compared with ratcheting alternatives.
• Not intended for non-crimp fitting systems, so it is specialized to F1807 style crimp connections.

Frequently Asked Questions

Are the supplied rings compatible with common F1807 fittings?
Yes, the annealed copper crimp rings are intended for crimp style fittings made to ASTM F1807 and equivalent standards.

Can the cutter be used on other plastic tubing?
The shear cutter is designed for PEX used in water applications; it will cut most similar soft plastic tubing but is optimized for PEX.

Is the crimper easy to use in tight spaces?
Yes, the angle head is specifically useful for working overhead and between joists, though some users report the need for firm hand pressure to complete crimps.
