ABSTRACT:
A universal swivel hose coupling which is adapted to be sealably connected to dissimilar externally threaded male fittings. The hose coupling includes a tubular stem having one end adapted to be received into the end of a hose and an opposite end having a forwardly facing frusto-conical surface. A nut is rotatably carried by the stem and includes an entry end portion at the outer end thereof. The frusto-conical portion of the stem is adapted to sealably mate with a male "flare" fitting having a conically tapered forward end conforming to the taper of the frusto-conical portion, and the entry end portion of the nut is adapted to sealably engage the O-ring of a male "straight thread O-ring boss" fitting.
