A pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.

A pipe sealing gasket is shown which is designed to be received within a raceway provided within the female, belled end of a section of plastic pipe which is assembled with a mating male pipe end to form a plastic pipe joint. The gasket is made up of a hard plastic band having an outer circumferential surface and an inner circumferential surface, and two separated elastomer portions. A first of the separated elastomer portions forms an outer ring which circumscribes the outer circumferential surface of the hard plastic band. The second of the separated elastomer portions forms an inner lip which circumscribes the inner circumferential surface of the hard plastic band. The two separate elastomer portions are connected during the gasket molding operation by a series of spaced ribs which form a continuous body of elastomer connecting the first and second separated elastomer portions at spaced intervals.

An assembly includes a tubular body having an axis, an axial end, a bore that is axial an aperture and a retainer groove formed in the bore and contiguous with the aperture. The assembly also includes a retainer mounted in the retainer groove. The retainer has a debris shield located external to the tubular body. The retainer includes a nominal configuration wherein the debris shield is configured to close off access to the aperture and the retainer groove to prevent debris from accumulating therein. In addition, the retainer includes an expanded configuration wherein the debris shield is not configured to completely close off access to the aperture and the retainer groove.
