The 3/4" ISO-B Female O-Ring Boss Coupler, Steel is a highly durable hydraulic coupling designed for secure, leak-resistant connections in fluid transfer systems. This coupler features an ISO-B Female O-Ring Boss (ORB) connection, which ensures a tight, reliable seal. The O-ring seal is strategically designed to prevent fluid leakage and contamination, even under high-pressure conditions. Made from high-strength steel, this coupler offers exceptional durability, corrosion resistance, and long-term reliability, making it ideal for a wide range of hydraulic, pneumatic, and industrial fluid systems.

Poppet valves prevent uncoupled leakage, with critical parts induction-hardened 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.
