Abstract
A mechanical joint restraint can include a one-piece, elastic 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, the gasket including: a main body positioned between the first gasket end and the second gasket end; a first stop lip extending radially inward from the main body with respect to the axis of the gasket, the first stop lip defining a first lip height; a gland positioned axially outward from the main body of the gasket with respect to the first gasket end with the mechanical joint restraint in an assembled condition; and a gripping ring positioned adjacent to at least one of the gasket and the gland.
