Hydraulic Fitting, 3/8"X3/8" Male Flat Face O-Ring

The 6G-6MFFOR Hydraulic Fitting is a 3/8" hose x 3/8" male flat face O-ring MegaCrimp® coupling designed for clean, dependable sealing in hydraulic systems where seepage isn’t “close enough.” Its patented MegaCrimp® “C” insert helps handle different hose constructions and wall thicknesses while distributing crimping forces evenly to form a concentric, leak-resistant seal—so your connection stays tight and your shop floor stays less… shiny.
