AN To Metric Thread Fitting

Precision Fluid Transfer Solutions for High-Performance Systems

For the serious tuner and automotive enthusiast, every connection is a potential failure point. Evil Energy fittings are designed to eliminate those risks. Our high-performance AN adapter fittings and AN fitting adapter units are CNC-machined from aerospace-grade T-6061 aluminum, ensuring they handle the extreme pressures of racing environments. Whether you are plumbing a high-pressure EFI system or a custom turbo oil line, our Evil Energy fittings provide the reliability required for a leak-free seal every time.

Seamless Integration: The Metric to AN Conversion Mastered

The biggest headache in modern tuning—especially with Euro and JDM platforms—is adapting factory metric fittings to standard AN lines. Our metric adapter fittings and metric to metric adapter solutions solve this with surgical precision.

  • Fuel Pump AN Fittings: Specifically engineered for high-flow pumps (Walbro, Bosch, AEM), our fuel pump an fittings ensure a high-volume transition from the pump outlet to your main fuel lines.
  • AN Adaptor Fittings & AN Adapter: Available in full size ranges, our an adapters feature a 37° flare surface to guarantee a mechanical seal that survives high-vibration environments.
  • Fittings Metric & Metric Adapters: From M10x1.0 turbo feeds to M22 oil cooler ports, our metric fittings adapters offer total coverage for any an to fitting conversion.

Why Pro Builders Trust Evil Energy Fittings

In a complex an to fitting setup, tolerance is everything. A poorly cut thread or a low-grade alloy leads to catastrophic leaks. Every AN fitting and an adapter fittings component from Evil Energy undergoes rigorous pressure testing. We focus on the details that DIYers and pros appreciate: deep thread engagement to prevent stripping and a hard-anodized finish for full compatibility with corrosive fuels like E85.

  • AN Fittings & AN Fitting: Maximum flow design to reduce turbulence.
  • Metric Adapter Fittings: Perfect for adapting fuel rails, sensors, and regulators.
  • AN Adaptor Fittings: The industry standard for custom oil and coolant plumbing.

    • Difference Between AN Size and Thread Size
    1. AN Size: Refers to the diameter of the fitting or hose. AN (Army Navy) sizes are standardized hose and pipe connection sizes, measured in 1/16 inch increments. For example, 4AN means the pipe's outer diameter is 4/16 inch (1/4 inch).
    2. Thread Size: Refers to the diameter and pitch of the thread, usually in metric or imperial units. For example, M12x1.5 means the thread diameter is 12 mm, and the pitch is 1.5 mm.
    • Check Specifications Carefully: Before purchasing, carefully check the specifications of your equipment and pipes to ensure you choose the correct AN Size and Thread Size.
