HYDRAULIC FITTING FOR BULKHEAD MOUNTING WITH KEY SHAPED CROSS SECTION

摘要

A hydraulic fitting is used to fluidly connect hydraulic hoses on opposite sides of a bulkhead (12) of a machine (10). The bulkhead (12) is clamped between a flange (36) of the hydraulic fitting and a nut (65). One set of threads of the hydraulic fitting is split by a flat surface (41) to create a cross section with a key shape that is received in only one orientation through a matched key shaped mounting bore (50) in the bulkhead (12). The key shape interaction prevents the hydraulic fitting from rotating when installed in the bulkhead (12).
