ABSTRACT:
A pipe coupling, comprising a sleeve having at least one end adapted for the insertion of a pipe and being provided with a substantially conically shaped supporting surface for a sealing ring. A compression ring is provided by which the sealing ring may be compressed around the pipe. The sealing ring is composed of a circumferentially compressible, but in cross section rather undeformable annular core, which is more particularly bent of a helical body having substantially circular windings, and a sheath of elastomeric material which forms the actual seal. The sheath completely encloses the annular core both cross sectionally and circumferentially. The supporting surface has a progressively decreasing diameter in the pressing direction.
