Hydraulic Fitting, 3/8"X1/2" Male O-Ring Boss

The 6G-8MB Hydraulic Fitting is a MegaCrimp® male O-Ring Boss (ORB) coupling designed for dependable, leak-resistant hydraulic hose assemblies. Featuring the patented internal “C” insert that helps evenly distribute crimping forces for a concentric seal, it’s built to work across different hose constructions and wall thicknesses—so the seal happens where it should, not “somewhere near the fitting.”
