Reducer AN -4 Female to -3 Male

The ALLSTAR PERFORMANCE Reducer AN -4 Female to -3 Male is a straight adapter fitting designed to connect larger -4 AN hose lines to smaller -3 AN ports and components. This product is essential for builders transitioning between different AN port standards within a single system, commonly found in custom fuel systems, cooling upgrades, and hydraulic brake installations.

Constructed from lightweight aluminum with a black anodized finish, this adapter provides a permanent, leak-free interface in fuel systems, coolant lines, and hydraulic circuits. The straight configuration minimizes flow turbulence and pressure loss compared to angled alternatives, while the female swivel end allows for 360-degree rotation, reducing installation stress on connected hose assemblies.

Racers and street performance enthusiasts rely on ALLSTAR PERFORMANCE fittings for their proven durability under sustained pressure cycling. The compact overall length of 2.05 inches allows for placement in confined engine bays and tight routing scenarios, making it ideal for racing, performance, and off-road applications where system reliability is critical.
