Abstract

The swivel screw fitting has a connector with a through-bore through which a hollow screw is screwed into a threaded hole in a connecting face. An upper and a lower soft O-ring (14) are fitted respectively in an upper and a lower annular chamber (13,13') which are formed by axially open annular recesses (11,12) in the hollow screw (3) and/or the connector and/or the connecting face. In the assembled state of the swivel screw fitting the O-rings seal the gap between the hollow screw and through-bore, and seal the connector in relation to the connecting face.
