3an to 1/4 NPT Adapter Fitting

The 3 AN to 1/4 NPT Adapter Fitting from EARLS is a precision fluid-system component designed for custom engine builds, fuel delivery systems, and hydraulic applications. This fitting is essential for builders and mechanics who need to bridge the gap between AN sizing and NPT infrastructure in their projects. It is particularly useful for fabricating fuel line assemblies, installing aftermarket gauges, or integrating performance cooling systems.

Manufactured to exacting tolerances, this adapter fitting is made from high-quality aluminum, ensuring consistent sealing performance across temperature and pressure cycles. The 3 AN (3/16" hose) to 1/4 NPT conversion allows for a secure connection between AN-sized hard lines or braided hoses and NPT-threaded ports. Precision machining of both the flared AN side and the tapered NPT side eliminates leaks that can occur with mismatched fittings.

Mechanics and engine tuners rely on EARLS adapters when retrofitting modern fuel systems into classic platforms or upgrading cooling circuits. The compact form factor of 1.5 × 0.55 × 2.95 inches fits easily into tight engine bays and transmission tunnels, while the lightweight design helps maintain balance in your build. This fitting is a reliable solution for anyone looking to enhance their vehicle's performance.
