Transition from copper to PEX faster and easier with these new adapters

With the launch of the industry’s first PEX expansion to copper press transitions, professionals now have a solution for a completely flameless piping system that eliminates the hassles, costs and hazards of soldering while also providing more efficient installs.

The new ProPEX® lead-free (LF) brass copper press adapters from Uponor are available in both male and female configurations, with the female adapters featuring an EPDM rubber O-ring for a dependable seal.

The offering features a patented design for securely fastening the pipe and fitting together, eliminating the need for a stainless-steel ring commonly used in large-dimension copper press fittings.

Compared to soldering copper, these new adapters reduce an overall project timeline by an average of 71%, helping to manage a project’s schedule and, ultimately, the bottom line. This new fastening system is available on 1/2-in. to 3-in. pipes. And because the adapters are backed by a 25-year transferable limited warranty, they offer additional confidence and peace of mind.

To get your hands on these new adapters, contact your local distributor. To learn more about the offering, visit
