Patent attributes
A device for coupling a male piping member to a female piping member includes 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 at least partially overlaps an overlapping surface of the gripping ring and communicates with the compressible sealing gasket. A locking ring surrounding the male piping member communicates 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.
