Hydraulic Fitting, 1/4"X3/8" Female Flat Face O-Ring 90Deg

The 4G-6FFORX90S hydraulic fitting is a 90° female flat face O-ring MegaCrimp® coupling designed for tight routing while maintaining a reliable, leak-resistant connection. MegaCrimp’s patented internal “C” insert helps distribute crimp forces evenly to form a concentric seal across different hose constructions—so you can make the turn without making a mess.
