The invention relates to a coupling (1) for placement in a hole such as a hole in a machine part or in a pipe (6) and around an insert (5) such as a pipe or an axle, where the coupling (1) is pipe shaped and includes at least a base part (2) and at least a first sealing part (3), which is suited for sealing against the insert (5) and at least another sealing part (4), which is suited for sealing against the hole part. The coupling includes at least one outgrowth (14) on the exterior, side of the coupling (1), where the coupling (1) includes an exterior surface (1') and an internal surface (1 "). The first sealing part (3) is mounted with contact against the inner surface (1") and is designed to seal against the insert (5) and the second sealing part (4) is mounted with contact against the outer surface (1') and designed to seal against the hole part. The invention also relates to the use of the coupling (1) for connections where there is to be controlled and / or sealed in a hole, including a pipe (6) and an insert (5) such as a pipe or an axle where the insert (5) can be moved in relation to the coupling (1) and ( or where filth on the insert (5) can be scraped off and / or where a conducting connection is needed between the insert (5) and the hole part, including a pipe (6) in order to prevent static electricity. With the invention it is achieved with a single item to ensure a 3A and EHEDG approved coupling, which functions as bush, friction bearing, scraper ring, sealing ring and conducting connection. |
