ProPEX expansion fittings leverage the thermal and elastic shape memory of Uponor AquaPEX® and Wirsbo hePEX™ pipe to make fast, reliable connections that grow stronger over time.

Developed by Uponor, this new solution takes the guesswork and freelancing out of piping installations. Each kit, which includes all the needed ProPEX® fittings, adapters, valves, and rings, is delivered to the job site — one kit per room or apartment — along with a material list and an isometric layout for the installer to follow, helping to minimize mistakes and maximize efficiency.
