#6 x #8 Male Reducer Fitting

The #6 x #8 Male Reducer Fitting from FRAGOLA is a precision-engineered AN adapter designed for fuel, coolant, and brake line systems where step-down port compatibility is critical. This straight-design reducer transitions from an 8 AN male port to a 6 AN male inlet, making it essential for custom fuel system builds, engine bay plumbing modifications, and high-performance cooling circuit layouts. Whether you're upgrading a carburetor feed line, rerouting a fuel cell system, or adapting manifold cooler lines, this fitting eliminates the need for multiple hose sections and maintains system integrity across different port sizes.

Manufactured from lightweight aluminum with blue anodized protection, the #6 x #8 Male Reducer Fitting resists corrosion and oxidation in engine bay environments while keeping weight to a minimum—critical for fuel system optimization on race and street builds. The anodized finish maintains conductivity for grounding purposes and provides consistent sealing surface durability across thermal cycles and vibration. The straight-body design minimizes turbulence and pressure drop, ensuring reliable flow rates in high-performance applications where fuel delivery precision directly impacts engine performance and safety margins.

This adapter is ideal for fabricators, fuel system specialists, and enthusiasts building custom fuel systems, turbo cooling lines, or brake fluid circuits where AN-sized components dominate the design. Installation requires standard AN wrench sizes and compatible AN hose fittings; always use proper thread sealant (PTFE tape or liquid) and verify line pressure ratings match your system requirements. Pair this reducer with FRAGOLA hose and matching AN fittings for a professional, leak-free system assembly that withstands sustained pressure and thermal stress.
