The union nut is screwed onto the socket component along a cylindrical and/or conical exterior thread. The ring gap between the union nut and the insert component is sealed. The ring gap between the union nut and the socket component is also sealed. The thread connection between the socket component and the union nut is positioned between the two sealing positions.
