Sealing ring for connecting the spigot of a corrugated pipe with a pipe socket having a smooth inside wall

摘要

The elastomeric sealing ring (19) for the end of a corrugated pipe fits between two corrugations (7, 8). It has lower lips which fit against the base (9) of the pipe, side lips (25 -27) which fit against the corrugations and upper lips (29 -31). These are rolled to one side when a sleeve (12) is pushed over the pipe end.
