#6 to 18mm x 1.5 O-Ring P/S Fitting

The #6 to 18mm x 1.5 O-Ring P/S Fitting is a precision straight adapter designed to connect 6 AN male ports to 18 mm x 1.50 male O-ring ports in hydraulic and fluid power systems. This RUSSELL fitting serves industrial, automotive, and tactical applications where reliable fluid transfer between SAE and metric port standards is critical. Engineered for durability and leak-free performance, this adapter is essential for custom fluid routing in high-pressure environments requiring secure, repeatable connections.

Manufactured from steel and finished with nickel plating, the #6 to 18mm x 1.5 O-Ring P/S Fitting provides corrosion resistance and extended service life in demanding conditions. The nickel-plated surface protects against oxidation while maintaining smooth threads and sealing surfaces, critical for maintaining system integrity under pressure. The straight configuration allows inline connections without offset, simplifying installation in compact layouts while the O-ring face seal delivers superior leak prevention compared to tapered thread designs, ensuring fluid containment in both static and dynamic applications.

This fitting benefits professionals and technicians assembling custom hydraulic systems, pneumatic manifolds, and fuel delivery networks that must bridge SAE (AN) and metric standards. Installation requires proper torque specification and compatible sealing materials; cross-reference your system pressure rating and fluid type to ensure compatibility. The compact dimensions and minimal weight make it ideal for space-constrained installations where multiple adapters support modular system configuration. Verify O-ring material compatibility with your working fluid before installation to guarantee optimal seal performance and system longevity.
