COUPLING AND METHOD FOR JOINING

摘要

A coupling comprising a first male part (1) and a second female part (2), where the male part is inserted into the female part and a ring shaped cavity thereby is formed between the parts. The cavity is delimited axially by means of a inner seal (4) and an outer seal (5). A bore (6) extending from the outer surface of the female part to the cavity (3) is used for injecting glue, and there is at least one bore (7) from the cavity (3) to the outer surface of the female part for venting air and draining excess glue. A seal (T) is placed in the bore (7) after the cavity is filled with glue, and some glue has drained through the bore (7), but before the glue has hardened. A method for establishing a permanent connection utilizing the coupling is described.
