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

The 6G-6FFORX hydraulic fitting is a MegaCrimp® female flat face O-ring coupling sized for 3/8" hose ID applications where you want a clean, dependable seal. MegaCrimp’s patented internal “C” insert helps distribute crimping forces evenly to form a concentric, leak-resistant seal across different hose constructions and wall thicknesses—so your hydraulics stay pressurized, not “expressive.”
