Series 1050 PP-R x HDPE Transition Submittal

HDPE Pipe x PP-R Pipe Transition Fitting

The transition fitting is constructed out of PP-R material and high-density polyethylene (HDPE) PE 4710 pipe. The fitting sleeve that joins the piping can be manufactured from epoxy-coated carbon steel or 304/316 stainless steel.  The PP-R and HDPE piping materials are hydraulically pressed into the machined coupling.  The transition fitting is designed with our multi-level barb system that provides a leak-free radial compressed joint.

Quality Assurance

The transition fitting shall be manufactured by Poly-Cam, Inc.  Poly-Cam, Inc. shall provide quality assurance with regards to proper installation, compatibility, performance, and acceptance.
