Hydraulic Male O-Ring Boss Plug, 5/8"

Hydraulic Male O-Ring Boss Plug, 5/8"

The 6408X10 Hydraulic Male O-Ring Boss Plug, 5/8" is a precision hydraulic fitting designed to securely seal unused ORB (O-Ring Boss) ports in hydraulic systems. Featuring a 5/8" thread size, this plug uses an integrated O-ring sealing surface to create a leak-resistant connection when tightened into compatible ports. Built from durable steel for strength and reliability, it helps maintain system pressure while protecting hydraulic components from contamination and fluid loss. It’s a simple but essential part—because in hydraulics, even a tiny open port can quickly turn into a very noticeable mess.
