Abstract
A hydraulic fitting is used to fluidly connect hydraulic hoses on opposite sides of a bulkhead of a machine. The bulkhead is clamped between a flange of the hydraulic fitting and a nut. One set of threads of the hydraulic fitting is split by a flat surface to create a cross section with a key shape that is received in only one orientation through a matched key shaped mounting bore in the bulkhead. The key shape interaction prevents the hydraulic fitting from rotating when installed in the bulkhead.
