Hydraulic Fitting, 3/4"X5/8" Female Flat Face O-Ring

The 12G-10FFORX Hydraulic Fitting is a MegaCrimp® female flat face O-ring (FFOR) coupling designed for reliable, leak-resistant hydraulic hose assemblies. With the patented internal “C” insert that helps distribute crimping forces evenly to form a concentric seal, it’s built to work across different hose constructions and wall thicknesses—so the only thing “flat” is the face seal, not your tire after driving through a puddle of hydraulic oil.
