RadiantPERT polyethylene raised temperature (PE-RT) tubing is constructed with five layers of material, giving it significant strength. The core and outermost layer are PE-RT, and sandwiched in the middle is an integral ethylene vinyl alcohol (EVOH) oxygen barrier. At the same time the five-layer tubing is more flexible and easier to install than other piping materials used in hydronic radiant heating, cooling, snow melting, and distribution piping applications.
RadiantPERT is manufactured with Dowlex™ 2344, which offers high temperature resistance and long life without cross-linking. The tubing has ratings up to 180°F (82°C) at 80 psi, and the EVOH barrier limits oxygen diffusion through the walls of the tubing to less than 0.10/m3/day at 104°F (40°C) water temperature.
RadiantPERT uses the same fast and reliable Watts Radiant connection systems that have been used with PEX for years, including CinchClamps™ stainless steel connectors, CrimpRings™ precision-formed, ductile copper connectors, and T-20 compression fittings.
The recyclable RadiantPERT tubing is certified to ASTM F2623 for PE-RT SDR 9 Tubing by NSF and CSA, and all RadiantPERT products are backed by a comprehensive 25-year warranty from Watts Radiant.
