Abstract
A mechanical joint restraint includes: a gasket defining an inner surface and an outer surface, the inner surface defining a bore, the bore defining an axis therethrough, the gasket defining a first gasket end and a second gasket end; a gland defining a bore defining an axis and positioned axially outward from the gasket with respect to the first gasket end with the mechanical joint restraint in an assembled condition, the axis of the gland aligned collinearly with the axis of the gasket; a gripping ring positioned between the gasket and the gland, the gripping ring being a split ring defining a pair of circumferential ends and a gap therebetween; and a bridge engaging each of the pair of circumferential ends of the gripping ring and extending in a circumferential direction of the gripping ring across the gap therebetween with the mechanical joint restraint in the assembled condition.
