The 6408X06 Hydraulic Male O-Ring Boss Plug is a high-pressure hydraulic fitting designed to seal unused SAE ORB ports in hydraulic systems. Featuring a 3/8" Male SAE O-Ring Boss (ORB) thread, this plug uses an O-ring sealing surface to create a tight, leak-resistant connection while maintaining clean system pressure. Manufactured from durable carbon steel and built for demanding hydraulic environments, it provides dependable performance for agricultural, industrial, and construction equipment. It’s a small component, but when it comes to hydraulic systems, a properly sealed port makes all the difference.
