<p>The gasket (1) has a front projection (2) at which an inner lip seal (5) is attached, where the lip seal is formed for attachment to an outer surface of a pipe. A groove (6) and an inner sealing surface are attached at the lip seal, and a front surface (8) is upward bent toward a middle axis of the gasket. A rear surface (9) is upward bent from a rear edge (4) of the gasket, where the front and rear surfaces run in an obtuse angle to each other. Stages (11, 12) are provided in a transition region (10) of the front and rear surfaces, where the region is formed in round shape at the stages.</p> |
