AN Reducer #8 Female x #4 Male

The AN Reducer #8 Female x #4 Male from Triple X Race Components is a precision adapter fitting designed for high-performance hydraulic and fuel system applications where line size reduction is critical. This straight-configuration adapter connects larger #8 AN (Academy National) female swivel ports to smaller #4 AN male connections, making it essential for custom fuel systems, racing engines, and hydraulic installations that require compact routing or stepped-down line transitions. Engineers and builders rely on these adapters to maintain system integrity while optimizing space and flow characteristics in demanding motorsport and industrial environments.

Manufactured from aluminum and finished in black anodize, this reducer combines lightweight durability with corrosion resistance—critical for long-term reliability in engine bays and high-vibration settings. The female swivel design on the inlet side allows full 360° rotation to accommodate hard-line or hose connections without binding, while the male outlet threads directly into receiving ports with precise AN thread geometry. Black anodized aluminum provides superior protection against oxidation and UV exposure compared to raw or clear-coated finishes, ensuring the adapter maintains its integrity across seasonal temperature variations and moisture-rich environments.

This adapter is ideal for fabricators, race teams, and restoration specialists building custom fuel delivery or hydraulic systems where line gauge transitions are unavoidable. The compact form factor (1.2 × 0.1 × 1.95 inches) fits tight engine compartments without sacrificing flow or introducing pressure drop beyond standard reducer specifications. Triple X Race Components' precision engineering ensures zero leak potential when installed with appropriate thread sealant, making this fitting a trusted choice for professional and amateur builders who demand reliability in high-pressure applications. Compatible with any system using standard AN fittings and hoses rated for #8 to #4 service.
