ABSTRACT:
A pipe having a sealing member (3) in an inner groove (2) at one pipe end (1). The sealing member provides a very effective seal relative to a spigot end (1a) of another pipe inserted in the pipe in question. The free ends of lip portions (6,7) of a sealing ring (4) (the cross section of which is of V-shape when undeformed) are provided with beads (8) so that behind a stiffening ring (5) surrounding said sealing ring (4) there is more volume of lip material than there is room for in the space confined by the adjacent part of the bottom of the groove (2), the exterior (1a') of said spigot end (1a), the rearmost sidewall (2') of the groove (2) and the stiffening ring (5). The pipe is preferably a plastic pipe.
