IWS-FA · four-size copper-ring PEX kit
Cover common copper-ring PEX sizes with one manual crimper and interchangeable inserts, plus preparation and inspection tools.
- Crimp sizes
- 3/8 in, 1/2 in, 3/4 in and 1 in
- Sizing arrangement
- Three removable inserts and the tool’s 1-inch jaw
- IWS-FA kit
- Crimper, inserts, PEX cutter, copper-ring removal tool, gauge and case
Why choose this configuration?
- One tool body covers four listed connection sizes.
- Preparation, removal and inspection tools help organize repair work without buying the same accessories twice.
Check before ordering: Copper-ring crimping is different from stainless-clamp cinching and PEX expansion. Select IWS-FA or IWS-FAS deliberately; individual jaw options contain no complete crimper.



Preparation and inspection
Select the correct jaw, prepare and position the ring, finish the crimp and inspect with the specified gauge. Check a removed fitting before any permitted reuse.
