ABSTRACT:
An elastomeric gasket for a segmented pipe coupling has ends which extend beyond the ends of the coupling segment, and which are retractable into skirt portions of the gasket formed at the respective ends thereof, the compressive force exerted on the end faces of the gasket being derived from the spring force stored in the gasket material when under compression and being substantially constant without regard to oversizing or undersizing of the pipes to be sealed.
