Abstract

A compression fitting is described that is suitable for connecting steel pipes as a first fit device. It comprises an externally threaded housing (40) having a bore for receiving a pipe (44) and a seat (50) around the bore, a polymeric or elastomeric sealing ring (52) adjacent the seat (50), a nut (60) engageable with the external thread thereby to urge the sealing ring (52) onto the seat (50), the housing (40) having an inwardly directed stop (46) within the bore adapted to prevent further insertion of the pipe (44), and a compressible or crushable element (48) in front of the stop (46). Further, a grip ring (58), with inwardly directed circumferential teeth- (66) on the inner axial face, can be provided adjacent the nut (60), for engagement with the exterior of the pipe (44) passing through the nut (60) into -the bore and to assist in hindering withdrawal, of the pipe if subjected to longitudinal forces.
