AN to O-Ring -10 x 3/4-16 (-8)

The AN to O-Ring -10 x 3/4-16 (-8) adapter from Triple X Race Components is a precision hydraulic fitting designed for high-performance automotive and racing applications where reliable fluid transfer is essential. This adapter bridges AN (Army-Navy) standard ports to O-ring face seal (ORFS) connections, making it ideal for custom fuel systems, brake lines, transmission coolers, and engine bay plumbing on modified vehicles.

The -10 port size indicates a nominal line capacity, while the 3/4-16 UNF thread specification (ORFS side) provides a robust mechanical connection that resists vibration-induced loosening common in race environments. The O-ring face seal design uses a captive elastomer ring to create a metal-to-metal contact point that distributes clamping force evenly, preventing both over-tightening damage and gradual seepage.

Professional fabricators and serious enthusiasts rely on this fitting when converting older carbureted fuel systems to EFI, upgrading brake cooling loops, or integrating aftermarket transmission systems. The adapter is designed to withstand extreme pressure and temperature cycles, making it a reliable choice for high-performance applications.
