AN Flare To ORB Adapter 1-5/16-12 (-16) to -10

The AN Flare To ORB Adapter 1-5/16-12 (-16) to -10 by Allstar Performance is a precision hydraulic fitting designed to bridge incompatible AN (Army-Navy) port configurations in high-pressure fluid systems. This straight adapter connects a 16 AN male O-ring port to a 10 AN male port, making it essential for custom fuel systems, brake lines, and cooling circuits where original equipment connections don't align. Motorsports builders, hot rod enthusiasts, and performance engine builders rely on these adapters to achieve leak-free connections without fabricating custom components.

Machined from aluminum and finished in black anodize, this adapter features an O-ring face seal (ORB) on the 16 AN side for superior pressure retention and leak prevention compared to flared fittings alone. The straight-flow design minimizes turbulence and pressure drop, critical in applications where system efficiency directly impacts cooling performance or fuel delivery consistency. At 0.13 lbs and compact 2.1 x 1.9 x 4.05-inch dimensions, it integrates seamlessly into tight engine bays without requiring bulky routing modifications or adapter stacking.

This adapter works best in custom cooling systems, fuel delivery upgrades, and brake line modifications where step-down fittings are unavoidable. Installers should verify port thread pitch and confirm both mating surfaces are clean before assembly to ensure proper O-ring seating. Allstar Performance's reputation for precision manufacturing makes this fitting a trusted choice for professional shops and dedicated hobbyists building competition-grade vehicles that demand absolute reliability under sustained high pressure and temperature cycling.
