Hydraulic Fitting, 5/8"X5/8" Male Boss O-Ring

The 10G-10MB Hydraulic Fitting is a male O-ring boss (ORB) hydraulic fitting built for dependable, leak-resistant connections in high-pressure hydraulic systems. Designed to work with MegaCrimp® couplings, it leverages the patented “C” insert concept that helps form a concentric seal by distributing crimp forces evenly across different hose constructions and wall thicknesses—so you can simplify inventory while keeping leaks where they belong: nowhere.
