ABSTRACT:
An adapter assembly having an intermediate ring and a screw-in part for a fluid plug-in system. The adapter assembly includes an externally threaded portion for threading into a threaded bore and an actuating shoulder. A receiving groove is formed in the transition between the actuating shoulder and the externally threaded portion with a first sealing ring is disposed therein. The intermediate ring fits onto the externally threaded portion and has opposing axially spaced annular portions. A first annular portion cooperates with the receiving groove and the actuating shoulder to form a first sealing chamber for the first sealing ring. A second sealing seat of a second annular portion facing away from the actuating shoulder cooperates with a surrounding surface adjacent to the bore and the externally threaded portion to form a second sealing chamber for the second sealing ring axially spaced from the first sealing chamber.
