Watts Radiant Slab PERT Tubing

Watts LogoThe next generation of slab heating tubing.

RadiantPERT is 5-layer tubing used for radiant heating, cooling, snow melting, and distribution piping. RadiantPERT offers high strength, high temperature resistance, and long life without cross-linking. It is the strongest flexible pipe on the market today when compared to alternative materials. RadiantPERT offers the greatest range of fitting flexibility as it can be used with ASTM F1960 Cold Expansion, CinchClamps, CrimpRings, and Compression fittings. RadiantPERT is manufactured with a DIN Standard barrier that makes it easier to pull through joists, reduces expansion noise, protects the oxygen barrier against moisture and job-site abuse. It is certified to ASTM F2623 for PE-RT SDR Tubing and carries a 30-year warranty for residential and commercial heating and snow melting applications.
