Abstract:
Disclosed is a device for coupling a male piping member to a female piping member including a compressible sealing gasket and a gripping ring surrounding the male piping member, the gripping ring including at least one gripping member and at least one overlapping surface; an intermediate ring surrounding the male piping member, the intermediate ring at least partially overlapping the overlapping surface of the gripping ring, the intermediate ring communicating with the compressible sealing gasket; and a locking ring surrounding the male piping member and communicating with the gripping ring, wherein through a tightening connection between the locking ring and the female piping member, the locking ring communicates with the gripping ring forcing the intermediate ring into the compressible sealing gasket to form a seal between the male piping member and the female piping member and subsequently to force the gripping ring to grip the male piping member.
