Hydraulic Fitting, 3/4"X3/4" Male Jic

The 12G-12MJ Hydraulic Fitting is a male JIC MegaCrimp® coupling designed to provide a dependable, leak-resistant crimp connection for hydraulic hose assemblies. Its patented internal “C” insert helps form a concentric seal by evenly distributing crimping forces, and it’s built to work with different hose constructions and wall thicknesses—so one coupling size can cover more hose variations (your inventory shelf will thank you quietly).
