A PEX pipe expander is a specialized plumbing tool used to expand PEX-A (cross-linked polyethylene) tubing so that a fitting can be inserted. Once expanded, the pipe contracts around the fitting, creating a secure, leak-proof connection without the need for clamps or crimp rings.
How It Works:
Insert the expansion head into the end of the PEX-A pipe.
Pull the trigger or manually expand the pipe to stretch it.
Quickly insert the fitting before the pipe contracts back to its original shape.
Wait for the connection to tighten, ensuring a watertight seal
