Abstract:
A pipe fitting includes a main polymeric body and a secondary polymeric body, of a different polymeric material, molded into and fixedly connected to the main body, so that the main body extends around the polymeric body. The secondary polymeric body extends around and is contiguous with a passageway of the pipe fitting, and at least partially defines a first opening of the passageway that is for being mated to a polymeric pipe. The main body extends around and is contiguous with the passageway, and at least partially defines a second opening of the passageway that is for being mated to a metallic pipe.
