Hydraulic Fitting, 3/8"X3/8" Male O-Ring Boss

The 6G-6MB Hydraulic Fitting is a MegaCrimp® hose end built for dependable, leak-resistant connections using a Male O-Ring Boss (ORB) thread. Designed for 3/8" hydraulic hose, it features the patented MegaCrimp “C” insert that helps accommodate different hose constructions and wall thicknesses while distributing crimping forces evenly to form a concentric seal. It’s the kind of fitting that prefers to do its job quietly—without turning your hose assembly into a surprise oil delivery service.
