Reducer Adapter Fittings -12AN x -20AN

The Reducer Adapter Fittings -12AN x -20AN from Vibrant Performance are essential plumbing components for any high-performance fuel, coolant, or brake line system where stepped port sizing is required. These adapters are designed to connect hose lines of different AN (Army-Navy) sizes without compromising flow integrity or introducing leaks. They are particularly useful in custom automotive builds, such as upgrading fuel systems or retrofitting cooling circuits.

Constructed from high-quality aluminum, the -12AN x -20AN design features a 12 AN male inlet that reduces to a 20 AN female outlet, enabling seamless transitions between larger and smaller diameter hoses. Vibrant Performance's reducer fittings are manufactured to strict tolerances to ensure leak-free sealing when paired with compatible hose ends and swaged fittings. This precision engineering is crucial for maintaining system integrity in demanding applications.

Mechanics and fabricators benefit from these reducer adapters when piecing together custom fuel rails, intercooler piping, and transmission lines. Their compact design allows for easy installation in tight spaces, making them ideal for various automotive projects. With optimized thread pitch and port geometry for AN or JIC standard hose end compatibility, these fittings eliminate cross-threading issues and reduce installation time.
