Abstract

A sealing ring (2) for a bushing of a pipe or fitting (especially consisting of plastic) contains a central sealing lip (10) and two additional lips (12, 14), arranged symmetrically with respect to a plane (4) of symmetry. Such a sealing ring is normally inserted into the bead of the bushing after production of the pipe or fitting and there is a risk that the sealing ring may fall out before production of the connection between the tip end which is to be inserted and the bushing or the pipe. The invention is based on the object of, on the one hand, arranging the sealing ring reliably in the bead and, on the other hand, producing an insertion resistance which is as small as possible. It is proposed that the additional lips (12, 14) be designed as strip-off lips having a larger internal diameter than the central sealing lip (10) and that in each case the base (20) of the intermediate spaces (16, 18) present between the said lips be arranged at a distance (24) from the outer surface (22) of the sealing ring (2), which distance (24) is essentially of equal size to the height (26) of the central sealing lip (10), likewise related to the base (20). <IMAGE>
