Pipeline seal fitted between two opposing cylindrical surfaces - has internal cavity, open to outside by aperture, and in which removable sliding aid is stored

摘要

A pipeline sealing ring (9) is fitted in the gap (10) between the cylindrical surfaces of a pipeline socket (12) and inserted pipeline end (11). The sealing ring has an interval cavity (7), open to the outside by an aperture (13). A sliding aid (4) is stored in the cavity and removed before assembly to help the pipeline end and socket slide together, without damaging the seal. ADVANTAGE - The sliding aid remains in perfect condition in the cavity until needed for assembly.
