Flare Reducer Adapter #6 to #8

The RUSSELL Flare Reducer Adapter #6 to #8 is a precision-engineered fitting designed for hydraulic and fuel line systems where port size conversion is essential. This straight adapter enables seamless connection between 6 AN female ports and 8 AN male connections, making it indispensable for custom fuel system builds, brake line modifications, and transmission cooler installations where existing line diameters don't match OEM or aftermarket component ports. Built for reliability in high-pressure applications, this adapter eliminates the need for costly component replacement when upgrading or retrofitting systems.

Machined from aluminum and finished with blue anodized coating, the Flare Reducer Adapter delivers corrosion resistance and lightweight performance critical for underhood environments. The straight design minimizes turbulence and pressure loss compared to elbow fittings, maintaining system integrity during high-flow operations—particularly important in modified engines pushing elevated fuel demands or upgraded cooling circuits. The anodized finish protects against oxidation while the aluminum construction keeps weight minimal, a consideration that compounds across multiple fittings in complex fuel and cooling systems. Its compact footprint (2.6 x 1.9 x 5.7 inches) ensures fitment in tight engine bays without compromising accessibility.

Mechanics and fabricators rely on this adapter when downsizing line runs from larger 8 AN manifolds to smaller 6 AN circuits, or when retrofitting components with mismatched port sizes. It's particularly valuable in vintage restorations, EFI conversions, and performance builds where fuel rail or cooler ports don't align with existing line gauges. Installation requires standard flare-nut wrenches and proper torque specification to prevent leaks—always verify system pressure ratings before assembly. This RUSSELL product (MPN 661770) meets automotive industry standards for reliability and is suitable for both street and track applications where leak-free hydraulic connections are non-negotiable.
