Aquatherm’s polypropylene-random (PP-R) piping systems now feature a new PEX compression adapter made of PP-R and lead-free brass. This adapter allows installers to easily transition between Aquatherm and PEX in potable water and radiant systems. Aquatherm’s new PEX adapter is entirely zero-lead and manufactured to ASTM F1960. A new male-end design allows installers to fuse directly into fusion outlets, making it quicker and easier to install, according to Aquatherm reps. The PEX adapter is available in .50-in., .75-in., and 1-in. diameters.
