Tip 1 – Understand How PEX Crimpers Work

To install PEX tubing with a water tight joint, you can use a crimping tool and crimp rings, but to be sure the joints will be water tight, you will need to know how to use your PEX crimping tool.

Tip 2 – Creating a joint

To create a joint in your PEX tubing, use a PVC pipe cutter, slide a crimp ring over the end of the tube. Then, onto the tube, push a PEX fitting and insert it into the tubing as far as possible. Then, position the crimp ring on the tubing about at 1/8 inch from the tubing tip. Open the crimper jaws by pulling apart its handles, position the jaws over a ring, and press the handles together until the ring is tightened enough onto the tubing that it creates a seal that will be water tight.
