Pipe Coupling Device

A sealing assembly for coupling a male piping member to a female piping member, the sealing assembly comprising:

• a compressible sealing gasket dimensioned to surround the male piping member;
• a locking ring dimensioned to surround the male piping member including at least one overlapping surface;
• and
• a gripping ring dimensioned to surround the male piping member and positioned between the locking ring and the compressible sealing gasket, the gripping ring having an inner surface and an outer surface, the inner surface including at least one gripping member, the outer surface including at least one overlapping surface and at least one slanted surface, the at least one overlapping surface of the gripping ring contacting the at least one overlapping surface of the locking ring, the at least one slanted surface contacting the compressible sealing gasket.

A pipe coupling device for use with a male piping member, the device comprising:

• a female piping member to receive the male piping member, the male piping member including
• an outer surface, the female piping member including
• an enlarged end portion dimensioned to surround the male piping member to define a sealing cavity between the enlarged end portion and the outer surface of the male piping member;
• and
• a cone-shaped portion having a larger end and a smaller end, the larger end connected to the enlarged end portion, the smaller end dimensioned no larger than the male piping member;
• a compressible sealing gasket arranged within the sealing cavity;
• a gripping ring dimensioned to surround the male piping member, the gripping ring having an inner surface and an outer surface, the inner surface including at least one gripping member and the outer surface including at least one overlapping surface;
• an intermediate ring dimensioned to surround the male piping member, the intermediate ring in communication with and at least partially overlapping the at least one overlapping surface of the gripping ring, the intermediate ring in communication with the compressible sealing gasket;
• and
• a locking ring dimensioned to surround the male piping member and to communicate 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 to force the intermediate ring into the compressible sealing gasket to form a seal between the male piping member and the female piping member and to subsequently force the gripping ring to grip the male piping member.
