Pipe connecting arrangement, comprising sleeve and separately produced ring attached to pipe by press fitting

摘要

The pipe (4) is inserted into the sleeve (3) serving as a component of a fitting (1) until its front edge touches a circular stop (7). A separately produced ring-shaped element (2.1) with a rounded outer surface and a gap (8) for the accommodation of a sealing ring (5.1) is positioned at the outer edge of the sleeve (3). The gap (8) has one slightly inclined vertical inner surface (14), facilitating the seal (5.1) to expand when the pressing device (10) acts on the connection.
