ABSTRACT:
A transition coupling for connecting a plastic natural gas supply pipe to a metal service pipe is comprised of substantially plastic components including a tubular non-metallic body and a non-metallic or plastic nut. A plastic nut is threadably connected to the body one at each end thereof for independently compressing seals within the body against the two pipes and separately gripping against the pipes to hold the pipes within the body. At one end of the coupling, a plastic gripper is wedged by the plastic nut to embed in the plastic pipe to anchor the plastic pipe in the coupling. At the other end of the coupling, a metallic gripper is used in conjunction with the other plastic nut to be wedged against and embed in the outside surface of the metal pipe. The metallic gripper is comprised of two segments, the outer surfaces of which are shaped to keep from embedding in the inside surface of the plastic nut and causing the nut to bind on the metallic gripper.
