Abstract

2.1 A pipe screw union is intended to be constructed such that the sealing ring (15) is still subjected to deformation forces even when the pipe (16) is displaced in the axial direction and at the same time drives the clamping ring (14). 2.2 In addition to the clamping ring (14) and the sealing ring (15), the pipe screw union according to the invention also contains a compression ring (13) which engages over the outer wedge surface and that end surface of the clamping ring (14) which faces the sealing ring (15). When the cap nut (11) is tightened, the compression ring (13) transmits the forces to the clamping ring (14) and to the sealing ring (15). If the pipe (16) is moved away from the basebody (12) of the pipe screw union (10), the compression ring (13) sticks in its position so that the deformation forces act on the sealing ring (15) as before. As a result of the movement of the clamping ring (14), it is pressed against the pipe (16) with an increased force. 2.3 The pipe screw union according to the invention is particularly suitable for gas-tight connections. <IMAGE>
