ABSTRACT:
A swivel hose coupling assembly and method provides a collar having an angularly inwardly disposed locking annulus. The angular disposition of the locking annulus permits a novel method of assembling the swivel hose coupling members.
In a preferred form, the assembly is designed for affixation to one end of an elastomeric hose, and includes a cylindrical insert having a serrated external surface at one end thereof, a shoulder at an opposing end, and a locking groove intermediate the serrated surface and shoulder. A fitting is rotatably mounted over the insert, the fitting having a mating shoulder for contact with the shoulder of the insert. An annular collar is concentrically positioned over an exposed end of the fitting, a first end of the collar containing the locking annulus being inserted first over the serrated portion of the insert. A force is then applied to the second end of the collar, causing the locking annulus to be forced against a rearwardly disposed wall on the fitting and to distort same radially inwardly into the locking groove of the insert. The result is a simple three-part assembly which may receive a hose end for conventional crimping between collar and insert.
