Abstract
A tube coupling for the detachable coupling of tube line sections of a high-pressure tubing system. The tube coupling includes two coupling blocks held together by a clamping screw, whereby one of the coupling blocks has a coupling plug that engages a plug socket provided on the other coupling block. A sealing ring is formed of a plastically deformable material and is enclosed between a front face of the coupling plug and a bottom-side sealing surface of the plug socket. In order to protect the sealing ring from being lost, damages and/or contaminated during assembly or opening and dosing the coupling, in a preassembled condition it is enclosed within a protective socket. To homogeneously load the sealing ring, the sealing ring is located at one point of a supporting triangle, the two other supporting points of being formed by a pair of supporting surfaces arranged side by side at an outer end of side flanges of the coupling blocks.
