ABSTRACT:
The invention relates to a threaded swivel connector (1) for connecting a housing (3) to a member (2) by means of a hollow bolt (7). For improving the sealing effect, there have been provided specially designed sealing edges (15) of a collar (8) of the bolt (7) to seal with the housing (3) and sealing edges (21, 25) of a sealing ring (18) between the housing (3) and the member (2) to be connected. The sealing edges (15, 21, 25) are formed between inclined annular faces (16, 17, 19, 20, 22, 23), one at an acute angle to a plane (E1, E2, E3) at right angles to said axis and the other oppositely inclined at a greater angle.
