Hydraulic Fitting, 3/4"X3/4" Female Komatsu 90 Deg

The 12G-12FKX90M Hydraulic Fitting (3/4" x 3/4" Female Komatsu 90°) is a Gates MegaCrimp® coupling designed to deliver a leak-proof, concentric seal for dependable hydraulic hose assemblies. Its patented internal “C” insert helps accommodate different hose constructions and wall thicknesses, distributing crimping forces evenly to simplify inventory by allowing one coupling size to work across multiple hose ODs on one- and two-wire hoses. This fitting features a 90-degree female Komatsu connection with M30 x 1.5 threads.
