Female Japanese Industrial Hydraulic Fitting

The 6G-6FJISX Female Japanese Industrial Hydraulic Fitting is a 3/8" MegaCrimp® coupling built to deliver a reliable, leak-resistant crimp connection for JIS-style hydraulic applications—because “it’ll probably seal” is not a maintenance plan. Using the patented MegaCrimp® design, the internal “C” insert helps accommodate varying hose constructions and wall thicknesses while distributing crimp forces evenly to form a concentric seal, reducing inventory headaches since one size can cover multiple hose ODs on both one- and two-wire hoses.
