The Aeromotive -12AN Bulkhead Fitting provides a secure, leak-free passage point for high-flow fuel lines through firewalls, fuel cells, and enclosure panels. Built for performance fuel system builders running AN-12 lines, this straight bulkhead fitting features male AN-12 threads on both ends and ships complete with a bulkhead nut and washer for immediate installation. Whether you are routing fuel supply lines through a custom fuel cell or creating a clean firewall penetration in a race vehicle, this fitting delivers the flow capacity and sealing integrity that serious builds demand.
Aeromotive machines this fitting from 6061 T6 aircraft-grade aluminum using precision CNC equipment, ensuring consistent thread geometry and optimal flow characteristics through the AN-12 bore. The Type II bright dip black anodized finish provides corrosion resistance and a professional appearance that matches other components in your fittings, hoses, and valves setup. Material compatibility extends to both gasoline and alcohol-based fuels, making this fitting suitable for pump gas street cars, E85 conversions, and methanol-burning race applications. The included hardware eliminates the need to source separate bulkhead nuts, simplifying your parts list when assembling fuel system plumbing.
This 12AN bulkhead fitting sees frequent use in fuel cell installations where supply and return lines must pass through the cell wall cleanly. Drag racers, road course competitors, and custom builders rely on proper bulkhead fittings to maintain system integrity under vibration and pressure cycling. Pair this fitting with -12 straight hose ends and compatible braided line for a complete fuel delivery solution. For builds requiring line termination, we stock -12 caps and -12 plugs to close unused ports.
This fitting is compatible with gasoline and alcohol-based fuels, including E85 and methanol. The 6061 T6 aluminum construction and anodized finish resist degradation from these fuel types, making it suitable for street performance and race applications.
Yes, Aeromotive includes a bulkhead nut and washer with this fitting. The hardware allows you to secure the fitting through panels up to the nut's thread engagement depth without purchasing additional components.
This is a straight bulkhead fitting with AN-12 male threads on both ends. One end passes through your panel or fuel cell wall while the other accepts a standard -12AN female hose end or adapter fitting.
While designed primarily for fuel systems, the aluminum construction and anodized finish can handle oil applications. For coolant systems, verify chemical compatibility with your specific coolant type before installation.
