Plug-in connector used as double socket for connecting two tube ends comprises sealing element arranged in annular groove in base body and having two sealing beads which lie on the inner surface of the tube ends in the form of O-ring seals

摘要

Plug-in connector comprises a base body (6), an annular sealing element (12), a clamping ring (50), and an annular body (20) which can be connected to the base body. A tube end (4, 5) against which the sealing element is arranged in a sealing manner can be tightened in the plug-in connector using the clamping ring. The sealing element arranged in an annular groove (14) in the base body has two sealing beads (60, 62) which lie on the inner surface of the inserted tube end in the form of two O-ring-type seals. Preferred Features: A deformation chamber (78) is provided between the sealing beads. The deformation chamber surrounds a connecting part (68) of the sealing element. The radial outer surfaces of the two O-rings integrated in the annular sealing element form the sealing beads. The O-rings are connected in one piece to each other by the connecting part.
