Watts Slab Heating PEX-AL-PEX

Watts RadiantPEX-AL for quality reliable systems.

RadiantPEX-AL is a 5-layer, cross-linked composite pipe engineered for radiant floor heating, snow melting, and distribution piping. It is constructed with a layer of aluminum between two layers of cross-linked polyethylene. RadiantPEX-AL provides superior pressure and temperature ratings along with the optimum blend of rigidity to hold itself in place for straight runs and enough flexibility to go around obstacles. RadiantPEX-AL has very little expansion/contraction, so it's ideal for dry applications or high temperature distribution piping. It also retains its flexibility in cold temperatures, so it can be easily installed in winter weather. For use with Compression fittings only. RadiantPEX-AL is manufactured in accordance ASTM F-1281-2005, and carries a 30-year warranty for residential and commercial heating and snow melting applications.
