ABSTRACT:
The invention concerns a coupling device for maximum pressure-tight threaded pipe connectors with a standard coupling body, with a 24 degree connector, a coupling nut to effect a pressure-tight connection, a standard pipe or a connection stub for connection to other system components, and a two-part ring whereby one ring is provided with a holding element which takes the form of a cutting or clamping ring and the second ring takes the form of a sealing ring (6) for the coupling body (1) and is positioned in front of the holding element (7). The sealing ring is provided with a stop face (10) which progresses radially to its ring axis (9) and, when fitted, abuts on to the inner ring face (11 ) of the coupling body (1) which extends over at least a part of the inner bevel face [cone] (2) of the coupling body (1). The sealing element presents a conically progressing sliding face (14) for the holding element (7) and a stop face (15) progressing radially to the pipe or ring axis (9). The sliding surface (14) of the sealing element (6) takes the form of a cone and is surface treated.
