Abstract
A sanitary line attachment (1) is provided which is of sleeve-shaped design in at least one front end region (6) and, in the sleeve interior of the sleeve-shaped front end region (6), bears an internal thread (7) for attachment to an adjacent line portion, wherein at least one sealing ring (9) is clamped in a sealing manner between the adjacent line portion and the line attachment. On the ring outer circumference of the sealing ring at least one holding projection (10) protrudes, which holding projection (10) engages in the internal thread (7) in the sleeve interior of the sleeve-shaped front end region (6). The sealing ring (9) is produced from a dimensionally stable and/or inelastic material, and the sealing ring (9) has at least one and preferably at least two indentations (11) which are arranged at a distance from one another on the ring inner circumference and are designed as tool engagement surfaces.
