Abstract (en)
[origin: CN113915355A] The present invention relates to a device (100) for connecting a gas-carrying pipe element (1), more particularly a hydrogen-carrying pipe element, to a counter-piece (2), more particularly a component, comprising: at least one threaded body (10), which is designed to be engaged tightly, more particularly gas tightly, with the counter-piece (2), a first seal (3), which is designed in the form of a valve body (3a), which is designed to be brought into contact, more particularly to be brought into gas-tight contact, with a valve seat (4) provided on the counter-piece (2) or is designed in the form of a gasket, and a second seal (5), which operates on a sealing action principle which exerts or develops the sealing action independently of an axial displacement, more particularly in a direction of insertion E, which is required to produce the sealing effect of the first seal (3).
