AN Expander #8 Female x #10 Male

The AN Expander #8 Female x #10 Male from Triple X Race Components is a straight adapter fitting engineered for high-performance hydraulic and fuel line systems in motorsports, racing, and performance automotive applications. This fitting enables seamless connection between #8 AN female and #10 AN male ports, solving common incompatibility challenges in engine bay plumbing and custom fuel delivery systems. Racers and performance builders rely on adapter fittings like this to maximize routing flexibility and achieve optimal system configurations without compromising flow or reliability.

Manufactured from aluminum and finished in black anodize, this fitting delivers corrosion resistance and a clean aesthetic suitable for exposed engine compartments. The aluminum construction keeps weight minimal—critical in racing where every fraction of a pound matters—while the black anodized surface provides durability against fuel, oil, and temperature cycling. The swivel design allows for easier installation and adjustment during line routing, reducing assembly time and stress on connected components. AN sizing (Army-Navy) is the industry standard for performance fuel and coolant systems, ensuring compatibility across premium racing fuel systems and custom builds.

This adapter is ideal for fabricators, race engine builders, and performance enthusiasts assembling custom fuel injection systems, turbo boost systems, or high-flow cooling circuits. The straight design and swivel female end provide clearance advantages in tight engine bays while maintaining leak-free connections under pressure. Installation is straightforward using standard wrenches or line wrenches; ensure proper torque specifications per your fuel system documentation to prevent leaks. Compatibility depends on your existing AN line configuration—verify both your female #8 and male #10 AN ports before ordering to ensure correct fitment.
