Waterline PEX Copper Tube Compression Adapter, 1/2 x 1/2-in

This copper compression adapter from Waterline joins copper tubing to cross-linked polyethylene (PEX) tubing, allowing you to easily connect existing 1/2-inch copper pipe to modern PEX plumbing. Made of lead-free copper, this compression fitting creates a secure, leak-proof connection between the two different tubing types, saving you the hassle of replacing your entire plumbing system if you only need to replace part of it. Simply slide the compression fitting over the copper tube, insert the PEX tubing, and tighten the compression nut to make a connection you can rely on for years.
