The 1" ISO-B Female O-Ring Boss Plug, Steel is a durable hydraulic fitting designed to securely seal unused ports in fluid transfer and hydraulic systems. This plug features an ISO-B Female O-Ring Boss (ORB) connection, which creates a tight, leak-resistant seal. Made from high-strength steel, this plug offers exceptional durability and corrosion resistance, making it ideal for use in high-pressure systems and harsh environments. The O-ring seal ensures a metal-to-rubber connection, minimizing the risk of fluid leakage and contamination while providing long-term reliability in fluid-handling applications.

Poppet valves prevent uncoupled leakage, with induction-hardened critical parts for durability and a dependable ball-locking mechanism that secures the mating halves. The socket and plug are precision-machined from solid barstock and use standard nitrile seals rated from -40°F to 250°F.
