| 20100078937 | Self Restrained Ductile Iron Fitting - A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. A ring-shaped body is installed within a mating groove provided in a mouth region of the as-cast fitting after the fitting has been cast at the manufacturing plant. The ring-shaped body is formed of an injection molded elastomeric material and carries a series of gripping segments which have teeth on an inner surface thereof which are designed to engage an outer surface of a mating male pipe. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening o f the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The gripping segments are mechanically bonded to the elastomeric body of the gasket during the injection molding operation. The ring-shaped body also includes a relatively flexible portion formed of an elastomer which forms a lip seal region with the mating male pipe. | 04-01-2010 |

In another embodiment of the invention, an annular recess adjacent the O-ring groove releasably receives a locking sleeve for a push-type connector for compressing the O-ring during insertion of a conduit. The sleeve is subsequently partially withdrawn and has an inwardly extending locking barb to engage the conduit, lockably holding the conduit in place. An outwardly extending gripping edge cams the locking barb as a locking wedge is inserted between the end of the socket and the annular flange of the sleeve. | 08-25-2011 |
