What are ProPEX® fittings?
Uponor’s unique ProPEX® cold-expansion fittings capitalize on the shape memory of Uponor PEX-a tubing. ProPEX connections require the use of one simple tool to make fast, strong, solid connections that hold tight in strength tests with up to 1,000 pounds of force, without the use of torches, glues, solvents or gauges.
