Abstract: A pipe fitting facilitates joining of a high-density polyethylene (HDPE) pipe to a polyvinyl chloride (PVC) pipe. The fitting has a HDPE body. A ring-shaped PVC insert is positioned within an inner surface of the body at one opening of the body. An inner surface of the PVC insert is threaded so that a PVC pipe that has a threaded outer surface can be screwed into the PVC insert.

Prior to installation, the inner diameter of the compression ring is smaller than the outer diameter of the portion of the body that surrounds the PVC insert. For this reason, when the compression ring is installed, the compression ring compresses the portion of the body that surrounds the PVC insert, holding the PVC insert within the body.
