Hydraulic Fitting, 3/4"X3/4" Male Flat Face O-Ring

The 12G-12MFFOR Hydraulic Fitting is a male flat-face O-ring MegaCrimp® coupling built for a secure, leak-resistant crimp connection on hydraulic hose assemblies. Inside, the patented “C” insert helps create a concentric seal by evenly distributing crimping forces, and it’s designed to work across different hose constructions and wall thicknesses—so you can cover more hose builds without turning your fitting inventory into a small museum.
