A sealing ring, including a supporting ring made of resin which is joined to a lip ring of elastomeric material. Also a method for manufacturing a sealing ring, that includes introducing a resin into a first cavity of a tool and subsequently hardening the resin so as to fabricate a supporting ring, introducing an elastomeric material into a second cavity of the tool and extruding the elastomeric material onto the supporting ring so as to fabricate a lip ring, hardening the elastomeric material so as to bond the lip ring to the supporting ring thereby forming the sealing ring, and removing the sealing ring from the tool.
