Hydraulic Fitting, 3/8"X3/8" Female SAE w/45-Deg Taper Seal

The 6G-6FSX Hydraulic Fitting is a 3/8" female SAE 45° (flare) MegaCrimp® coupling designed to deliver a reliable, leak-resistant crimp connection for hydraulic hose assemblies. Built with MegaCrimp’s patented internal “C” insert, it helps accommodate different hose constructions and wall thicknesses while distributing crimp forces evenly to form a concentric seal—so your connection stays tight without needing a “just snug it again” routine.
