Description
ColorFittings AN to Metric Adapter and Union Fittings are precision-engineered to connect metric female ports to AN flare fittings, providing a secure, leak-free solution for fuel, oil, coolant, and power steering plumbing systems.
Each adapter is CNC machined from 6061-T6 billet aluminum and finished with ColorFittingsโ proprietary polishing and anodizing process for maximum strength, corrosion resistance, and long-term durability. These fittings are designed to withstand high pressure and high temperature environments commonly found in racing, street performance, marine, and aviation applications.
Our AN to Metric Adapters are manufactured to provide a perfect fit and seal when paired with ColorFittings AN fittings, which are specifically engineered for use with E85, ethanol-based fuels, and race fuels. When combined with our nylon or stainless steel braided hose, these adapters deliver reliable performance and clean routing for any high-performance plumbing system.
For best installation results, we strongly recommend using our AN Fitting Assembly Tools, which help prevent fitting damage and ensure proper hose and fitting alignment. Please reference our installation video and fitting guide for proper assembly techniques and torque recommendations.
