AN Male Reducer #3 x #4

The TRIPLE X RACE COMPONENTS AN Male Reducer #3 x #4 is a precision-engineered aluminum adapter fitting designed for high-performance fluid and pneumatic line integration in motorsports and industrial applications. This straight adapter reducer transitions from a #3 AN (Anderson) male port to a #4 AN male port, enabling seamless connection between incompatible line sizes without requiring additional hose sections or bulky connectors.

Constructed from lightweight aluminum and finished in black anodize, this fitting offers corrosion resistance and durability in demanding environments. The black anodized finish protects against oxidation and provides a professional appearance common in race car fuel systems, pneumatic brake lines, and nitrous oxide delivery systems. At 0.03 lbs, the minimal weight makes it ideal for competition builds where reducing overall mass is critical. The straight configuration ensures direct flow with no dead spots, important for fuel delivery consistency and pressure stability.

This adapter is essential for builders working with mixed AN line sizing in fuel injection systems, turbo drain lines, radiator connections, and transmission cooler circuits. It's a go-to solution when transitioning between different gauge requirements without redesigning an entire line assembly. The #3 to #4 AN step-up is commonly encountered in manifold connections and firewall bulkhead fittings.

TRIPLE X Race Components maintains a reputation for precision motorsports fittings that meet industry standards for aerospace and racing applications. Part number HF-36304BLK is sold individually, giving you flexibility to source exactly the quantity needed for your project.
