Description
When routing fuel, coolant, or pneumatic lines through your race engine bay, adapter fittings are non-negotiable—they ensure leak-free connections between incompatible port standards and eliminate costly system failures. This AN to NPT straight adapter bridges the gap between 4 AN hose fittings and 1/4 in NPT threaded ports, making it essential for custom fuel systems, cooling upgrades, and forced induction setups. The black anodized aluminum construction resists corrosion while maintaining a lightweight profile ideal for performance builds.
