ABSTRACT:
The present invention is a hydraulic coupling and method of making the same. The coupling includes a male fitting, a female port, and a lock nut. The male fitting has external threads which receive the female port and the lock nut. The female port has an internal tapered recess for mating with an external tapered surface of the skirt of the lock nut. The skirt portion has inner and outer sections which initially form a double angle on the exterior surface. The outer section is bent inwardly to form a tapered external surface forming a steeper internal angle with the male fitting. An O-ring is positioned about the male fitting for sealing the hydraulic coupling within the tapered recess. The fitting of the present invention is also adaptable to the O.R.S. fitting and the S.A.E. flange fitting. A tapered surface of the female port engages an O-ring positioned in an annular groove of the male fitting.
