Abstract
A self-compensation gasket for grooved end pipe couplings for use in sealing the joint between the pipe ends. An "immediate" seal at the pipe end gap serves as a barrier to possible entry of solids into the internal working section of the gasket. Compression pads on the outside diameter of the gasket concentrate the loading of the gasket in a localized manner such that a high compression loading may be insured.
