Abstract
A sealing ring for sealing off a joint between a fluid power line and a fluid power component to be connected therewith. At one axial side the sealing ring has two overpressure sealing lips arranged in a v configuration. At the opposite axial side a thrust portion is provided for cooperation with a gripping element. The thrust portion and an inner underpressure sealing portion provided thereon define a radially moving pivot ring. If the fluid power line is under vacuum, the pressure of the surroundings causes the pivot ring to be shifted inwards and the underpressure sealing portion is thrust sealingly against other surface of the fluid power line.
