Watts Radiant RadiantPEX-AL Compression Fittings (Heating Only - Not for Potable)

RadiantPEX-AL is a composite pipe engineered for radiant floor heating. We call it ALEX Pipe. It's proven, long lasting and maintenance-free. Installers like it because it's lightweight, durable and can be shaped to fit any jobsite. The aluminum layer protects boiler systems against corrosion and it has superior temperature and pressure ratings.

ALEX Pipe is manufactured to American Standard Testing Methods for composite radiant pipe and fittings (ASTM F-1281). Included are requirements and test methods for materials, workmanship, dimensions, environmental stress cracking, sustained hydrostatic pressure strength, thermo-cycling resistance and bend strength among other tests. RadiantPEX-AL meets or exceeds these specifications.
