Since its inception in 1973, Aquatherm has been the innovation leader in engineered polypropylene piping. Connected by reliable heat fusion, Aquatherm delivers long-lasting easy-to-install systems for potable, heating and cooling, and industrial applications. To accommodate projects of nearly any size, Aquatherm pipe is available from ½" to 24" in diameter. Aquatherm's pipes and fittings are made from polypropylene random PP-R and/or PP-RCT, thermoplastics that provide many advantages in piping systems, including heat-fused connections and naturally corrosion-resistant properties. A wide range of transitions such as flanges, PEX adapters, brass and steel threads as well as copper stub outs, make integration with other systems simple.
