Uponor PEX-a Tubing & ProPEX® Connection Animation

Learn about the unique properties of Uponor PEX-a tubing and the ProPEX® connection technology for PEX plumbing, fire sprinkler and radiant heating and radiant cooling systems. PEX stands for crosslinked polyethylene, which is a flexible and durable piping product that has been used in plumbing systems for more than 20 years. PEX-a is the most flexible of all PEX types, and because of its shape and thermal memory, it can use ProPEX® expansion fittings which are the only fitting system that actually gets stronger over time. Uponor provides PEX tubing used in radiant floor heating and cooling, PEX plumbing and fire sprinkler systems; all with commercial and residential applications.
