Hydraulic Fitting, 1/4"X3/8" Male Pipe

The 4G-6MP Hydraulic Fitting is a MegaCrimp® coupling designed for 1/4" hydraulic hose with a 3/8" male pipe connection, delivering a consistent, 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—so the fitting seals like it should, not like it’s negotiating.
