There is disclosed a three bolt breakaway coupling adapted to be connected to either one or both ends of a flexible fluid conduit having a housing at each end that may include a valve. The breakaway coupling has two generally triangular shaped flanges where each flange has a central opening surrounded by a sealing member such as an 0 ring and an opening located at each corner of each triangular shaped flange for receiving a shear bolt. At least two of the three shear bolts which couple the two triangular flanges together will break when a specified pull at any angle is applied to the three bolt breakaway coupling. The first and second housings may contain valves for controlling the flow of a fluid through the conduit.
