Hydraulic Fitting, 1/4"X1/4" Male Boss O-Ring Swivel

The 4G-4MBX Hydraulic Fitting is a 1/4" x 1/4" Male Boss O-Ring swivel fitting engineered for dependable, leak-free hydraulic connections. Featuring the patented MegaCrimp® coupling system, this fitting uses an innovative internal “C” insert that distributes crimping forces evenly to create a concentric, leak-proof seal. The design allows one coupling size to accommodate multiple hose constructions and wall thicknesses—simplifying inventory while maximizing performance. In short, it’s built to seal tight and stay that way.
