Pipe fitting

摘要

A compression pipe fitting is provided. The fitting comprises a body defining one or more sockets for receiving an end of a pipe, a clamping nut and a grip ring. The socket is encircled by a threaded face, and is internally adapted to receive a compressible O-ring. The nut can be screwed onto the threaded face of the socket and has an internal tapered surface while the grip ring has a complimentally tapered surface which, when the nut is tightened onto the threaded face, bears upon the grip ring compressing it against the pipe and compressing the o-ring located within the socket.

1. A push-fit compression pipe fitting comprising a body defining one or more sockets for receiving an end of a pipe, the socket being encircled by a threaded face, and including a seat and a compressible O-ring received within the seat, a clamping nut which can be screwed onto the threaded face, and a grip ring; the internal surface of the nut and the external surface of the grip ring being complementally tapered and engaged in full and complete abutment when the nut is tightened onto the threaded face;
wherein tightening of the nut results in linear compression of the O-ring between the seat of the socket and the grip ring, consequently reducing the diameter of the O-ring to create a sealing fit around the pipe, wherein the grip ring comprises a stainless steel split ring embedded within a plastic composite material.
