Abstract A novel fluid coupling, a novel tool for removing a coupling seal from the novel fluid coupling, and the method of utilizing the coupling seal removal tool. The coupling 10 includes a check valve 58 which has a skirt portion 64 normally disposed within a coupling seal when either a male coupling 12 is connected to it, or when the male coupling has been removed. The female coupling is so designed that the skirt of the check valve can be entirely shifted outside of the coupling seal 62 when the novel seal removal tool 68 is inserted into the open end of the coupling. The tool is provided with a knife edge (between surfaces 82 and 84) which can engage the inner annular surface of the seal 62 and cause the seal to he removed when the tool is removed from the open end of the female coupling.
