Watts RadiantPEX+ Slab Heating PEX Tubing

American made tubing for quality reliable systems.

RadiantPEX+ tubing with EVOH (oxygen barrier) is a 4-layer tubing used for radiant heating, snow melting, and distribution piping. This cross-linked tubing offers high flexibilty, high temperature resistance, and long life. It can be used with CinchClamps, CrimpRings, and Compression fittings. The extra low-friction outer layer makes it easier to pull through joists, reduces expansion noise, and protects the oxygen barrier against job-site abuse. RadiantPEX (3-layer) and RadiantPEX+ is manufactured to ASTM F-876 and F-877 and to SDR9 dimensions and carries a 30-year warranty for residential and commercial heating and snow melting applications.
