Attachment fitting with frictional linear compensator for water pipe conduits

摘要

The fitting consists of a tubular sleeve (10) provided with a thread running along part of its length. The sleeve is designed to be screwed into a mating part having a sealing surface and on the other end, a lock nut (1). The lock nut is built in a polygonal fashion on its inner contour (12), the sleeve having a region between its end and the threaded region which has a corresponding outer contour (3). The polygonal contour is octagonal. The sleeve has at least one seal at its end facing away from the lock nut, where the seals are in the form of O-rings.
