Hydraulic Fitting, 1/2"X3/4" Male O-Ring Boss

The 8G-12MB Hydraulic Fitting is a MegaCrimp® coupling designed for 1/2" hydraulic hose with a 3/4" Male O-Ring Boss (ORB) connection for a dependable, leak-resistant crimped assembly. Its patented internal “C” insert helps accommodate different hose constructions and wall thicknesses while distributing crimping forces evenly to form a concentric seal—making your hose build more predictable and your shop floor less “hydraulically moisturized.”
