4AN 1/4NPT to 2AN 1/8NPT Male Female Reducer

The 4AN 1/4NPT to 2AN 1/8NPT Male Female Reducer by REDHORSE PERFORMANCE is a vital hydraulic adapter designed for custom fuel, oil, and coolant line configurations in performance and modified vehicles. This reducer fitting allows mechanics to transition from larger 4AN supply lines to smaller 2AN branch lines, ensuring reliable connections without compromising flow integrity or system pressure ratings.

Featuring a male 1/4NPT port on one side and a female 1/8NPT port on the other, this adapter provides flexible orientation during installation based on specific line routing needs. The precision-engineered design maintains consistent wall thickness and internal passage diameters to minimize turbulence and pressure drops. REDHORSE PERFORMANCE fittings are manufactured to strict aerospace standards, ensuring durability under high-pressure fuel systems and extreme temperature cycling.

This reducer is ideal for builders transitioning from main fuel lines to secondary regulators, gauge feeds, boost-referenced systems, or return lines in modified EFI setups. Its lightweight design (0.05 lbs) and compact dimensions make it suitable for tight engine bays where space is limited, providing a reliable solution for complex plumbing applications.
