The 3AN to 4AN Reducer Black Male Male from REDHORSE PERFORMANCE is a precision hydraulic and fuel line adapter designed for high-performance automotive, racing, and industrial fluid systems. This fitting transitions from a 4 AN (5/16-inch) male port to a 3 AN (1/4-inch) male port, making it essential for builders who need to step down line sizes while maintaining system integrity.
Constructed from aluminum and finished with a black anodized coating, this fitting offers corrosion resistance and durability in demanding environments. The anodized surface protects against oxidation while the aluminum core maintains an excellent strength-to-weight ratio, which is critical for racing platforms where every fraction counts. The straight design ensures minimal turbulence and pressure drop across the reducer, preserving flow efficiency and system performance.
Engine builders, custom fabricators, and performance technicians rely on REDHORSE AN fittings to create clean, reliable plumbing in fuel injection systems, turbocharger circuits, and modified cooling loops. The compact dimensions of the fitting allow it to fit into tight engine bays, making it a versatile choice for various applications.
