The REDHORSE PERFORMANCE 3AN to 4AN 1/4NPT Straight Male to Male adapter is an essential hydraulic line connector for custom fuel, coolant, and brake system builds. Proper fitting selection is critical for performance mechanics, as mismatched AN fittings can lead to leaks and pressure loss.
This straight adapter bridges two different hose sizes while maintaining NPT port compatibility, featuring male-to-male threads on both ends. It is constructed from aerospace-grade aluminum with an anodized finish to resist corrosion, ensuring durability in harsh environments.
Engine builders and fabricators benefit from this adapter when transitioning between legacy carbureted fuel systems and modern EFI setups, or when adapting oversized radiators to factory NPT ports. Installation requires standard AN wrench sizes and proper Teflon tape on the NPT thread to prevent seepage.
