ABSTRACT:
A swivel coupling device is designed for coupling together the mating ends of two tubular fittings forming part of a pressurized fluid, fuel or gas connection system between a fluid, fuel or gas supply and an output device. The device has two relatively rotatable coupling parts with mating flat faces rotatably secured together in face-to-face engagement. Each of the flat faces has a recess with a circular outer periphery matching that of the recess in the other part, and each part has a passageway extending through it to the recess from a point on its outer surface remote from the flat face. Suitable connecting fittings are provided for connecting the passageway on each part to a respective tubular fitting so that the fittings can be swivelled, via dual axes, omni-directionally, relative to one another while fluid, fuel or gas communication between the fittings is maintained through the passageways and recesses of the coupling.
