The pipe can then be axially fixed in the inserting opening by a holding part which can be mounted on the connecting body. The insertion-type connection provides long service life of its sealing ring under extreme conditions. For this purpose, the supporting ring is equipped on its face which faces the sealing ring with a sealing lip which sealingly encloses the pipe end piece. As a result, it is achieved that, when acted upon by pressure, the sealing lip, independently of component tolerances, is pressed in a form-locking manner against the circumference of the pipe end piece.Type: GrantFiled: June 14, 1993Date of Patent: February 20, 1996Assignee: Hydraulik-RingInventors: Axel Sauer, Gunther Wiesner, Frank van de Poel, Kurt Schaible

Patent number: 5472242Abstract: For use in push-in-and-snap pipe connectors, the region of the pipe behind the integral end-flange is raised in diameter. If the pipe is properly inserted, the raised region is concealed inside the body of the fitting; but if the pipe is not pushed fully home into the body, the raised region is visible, and serves to alert the production-line inspector that the joint is not sealed. A snap-in sping clip holds the pipe in the body, and the clip rests against the raised protion to minimise the chance of vibration noise. The flange and raised region are formed in the pipe by axial-press punches and dies.Type: GrantFiled: June 24, 1994Date of Patent: December 5, 1995Inventor: Horst U. Petersen
