Hydraulic Fitting, 1/4"X1/4" Female Flat Face O-Ring 45Deg

The 4G-4FFORX45 Hydraulic Fitting is a 45° female flat-face O-ring MegaCrimp® coupling built for smooth routing and a leak-resistant crimp connection on hydraulic hose assemblies. The patented internal “C” insert helps deliver a concentric seal by evenly distributing crimping forces, and it’s designed to handle different hose constructions and wall thicknesses—so one coupling size can cover more hose variations (your parts bin just sighed in relief).
