摘要

A sealing ring to be mounted on the outside of a tubular element (11) for use in a fluid-conducting duct system comprises a base (13) with a fastening section which is adapted to be clamped by an end portion (18) of the tubular element (11), and a sealing section having at least one sealing lip (16) adapted to seal against the inner surface of an outer tube, in which the tubular element (11) is inserted. The sealing section comprises a main sealing lip (14) extending substantially radially away from the base (13) of the sealing ring (10), and at least one intermediate sealing lip (16) which is disposed between the main sealing lip (14) and the fastening section and which extends substantially radially away from the base (13) of the sealing ring (10). The intermediate sealing lip (16) is adapted to seal against the inner surface of the outer tube.
