Hydraulic Fitting, 3/4"X3/4" Female Flat Face O-Ring

The 12G-12FFORX Hydraulic Fitting is a female flat face O-ring hydraulic coupling designed for dependable, leak-resistant connections in demanding hydraulic hose assemblies. Built with the MegaCrimp® system’s patented “C” insert, it helps create a concentric seal by evenly distributing crimping forces while accommodating different hose constructions and wall thicknesses—simplifying inventory by allowing one size to fit multiple hose ODs on one- and two-wire hoses.
