发明名称 Tubular element with sealing means and a method for manufacturing the tubular element
摘要 A tubular element has a sealing ring mounted at an end of the tubular element. The sealing ring has a base clamped against the outer surface of the tubular element. Further, the sealing ring has a sealing lip adapted to seal against an inner surface of an outer tube, in which the tubular element is inserted. The base is disposed in a groove that is formed in the wall of the tubular element. The sealing ring has a further lip that is positioned adjacent to the end of the tubular element and that is bent down and clamped against the base by means of the end portion, thereby providing secure fastening of the sealing ring. The sealing ring is fastened by a method involving bending of the end portion of the tubular element together with the further lip.
