AbstractA threadless nonrotating steel coupling system that is quickly connected and disconnected in an axial manner by simple hand tools, is sealed by a compressible gasket, and is locked together by a pin system to prevent rotation of the male half-coupling relative to the female half-coupling. The coupling is held together by means of matching circular saw-toothed ridges and grooves at right angles to the axis of the coupling, which substitute for the pitched threads used in standard threaded coupling systems. The steel male half-coupling is rigid whereas the steel female half-coupling, which contains a series of spring-loaded and parallel longitudinal fingers, is flexible, since each steel finger is free to move in a radial direction with respect to the axis of the coupling system.
