Hydraulic Fitting, 3/4"X3/4" Male O-Ring Boss Swivel

The 12G-12MBX Hydraulic Fitting (3/4" x 3/4" Male O-Ring Boss Swivel) is a MegaCrimp® hydraulic hose coupling built for a secure, leak-resistant crimped connection in demanding hydraulic systems. Its patented internal “C” insert helps accommodate different hose constructions and wall thicknesses while distributing crimp forces evenly to form a concentric seal—helping simplify inventory by allowing one size to cover a wider range of hose ODs on both one- and two-wire hoses.
