IWS-2538CF Prensadora para cobre Viega ProPress, 1, 1 1/4 y 1 1/2 pulg.

Match the fitting system—not just the tube diameter

Use the jaw for the marked nominal fitting size and confirm the tube, fitting series and required press profile together. Brand names alone are not universal compatibility approval.

This is not a PEX, refrigerant RLS/ZoomLock or European metric press kit. Similar-looking jaws or close dimensions do not make those systems interchangeable. A tool listing is not a pressure rating for the finished piping system.

What to check in the kit

The configuration is IWS-2538CF with the three listed jaw sizes and the listed socket wrench. A driving impact wrench is not included. Confirm the current packing list before buying additional accessories; do not order an extra jaw simply because it appears in related products.

Manual or impact drive: choose for the job

The US listing recommends impact-wrench operation for sizes 1 inch and larger. Use only a drive, socket and operating setting permitted by the tool instructions; do not infer an impact torque rating from fitting size.

The detachable arrangement helps positioning, but the required work envelope includes the jaw opening and the driving wrench. Confirm access around the whole fitting before starting.

Prepare, press, release and test

1. Verify the fitting system, tube specification and the matching jaw size.
2. Cut square; deburr, clean, check the sealing element and mark insertion depth as specified by the fitting manufacturer.
3. Insert the tube fully and position the jaw squarely on the fitting’s press contour.
4. Complete the prescribed drive cycle, then release the tool following its instructions.
5. Inspect the press and carry out the required system pressure or leak test before service.

The LED is a completion indicator, not a leak detector. It does not certify a sealed joint or replace system testing.
