Aquatherm’s polypropylene-random piping systems feature a straight, threadless transition from PP-R pipe to copper-sweated connections. With straight Aquatherm-to-copper stub-outs — which come in 1/2”, 3/4” and 1” diameters and are 11”, 11” and 18” long, respectively — installers can easily transition to a fan-coil unit, zone valve, heat pump or other HVAC components with sweated connections using PP-R.

The PP-R portion is mold-injected PP-R and is connected via heat fusion. The copper portion is connected using standard copper solder joints or compression fittings.
