Hydraulic Fitting, 1/4"X3/8" Female Flat Face O-Ring 90Deg

The 4G-6FFORX90M Hydraulic Fitting is a 90° female flat-face O-ring MegaCrimp® coupling designed for a dependable, leak-resistant crimp connection on hydraulic hose assemblies. Its patented internal “C” insert helps create a concentric seal by evenly distributing crimping forces, and it’s engineered to work across different hose constructions and wall thicknesses—so your inventory can stay lean instead of multiplying like rabbits in spring.
