ABSTRACT:
This invention relates to a compression joint of the type used to connect the end of a piece of compressible pipe to a corporation fitting such as a curb stop, a main stop or a ball valve. The pipe is usually soft copper the wall of which is compressible, but it can be plastic and may, in the future, tend to be plastic rather than copper. The joint includes a nut threaded onto a sleeve; the nut and sleeve and an inserted pin forming a chamber which receives a split compression ring, a spacer tube, and a compressible gasket. The compression ring and gasket are urged into engagement with the pipe when the size of the chamber is reduced as the nut is threaded onto the sleeve.
