Aquatherm’s polypropylene-random (PP-R) piping systems, which are increasingly being used in a variety of PHVAC applications, now feature a straight, threadless transition from PP-R pipe to copper sweated connections. This new transition allows for installations to be more easily fitted out entirely in PP-R, particularly on commercial and industrial plumbing applications using Aquatherm.
Now with straight Aquatherm-to-copper stub-outs, which come in ½-inch, ¾-inch, and 1-inch diameters, and are 11-in., 11-in., 18–in. long respectively, installers can easily transition to a fancoil unit, zone valve, heat pump, or other HVAC components with sweated connections using PP-R. Aquatherm teamed up with Sioux Chief Manufacturing to create this new stub-out, which represents a more mainstream transition method for copper sweated connections.
The PP-R portion of the stub-out is mold-injected PP-R manufactured in Germany from the same material as Aquatherm Green Pipe® and Aquatherm Blue Pipe® (formerly Climatherm®) and is connected via heat fusion. The copper portion of the stub-out is manufactured in the U.S. by Sioux Chief and is connected using standard copper solder joints or compression fittings. The fitting is a combination of a custom Aquatherm PP-R socket with the copper added by Sioux Chief. The fused PP-R portion is covered under Aquatherm’s warranty and the copper portion is covered under a Sioux Chief warranty.
All Aquatherm systems are connected via heat fusion – which bonds the pipe and fitting at the molecular level creating joints that last a lifetime while eliminating toxic materials, glues and resins, and open flames from piping installations.
