6AN to 8AN Reducer Black Male Male

The REDHORSE PERFORMANCE 6AN to 8AN Reducer Black Male Male fitting is a straight-pattern adapter designed to connect hydraulic or fuel system lines of different sizes within high-performance applications. This 919 Series aluminum adapter reduces line diameter from 8 AN to 6 AN, enabling flexible system routing in vehicles where space constraints or existing component layouts require a size transition. The black anodized finish provides corrosion resistance and a professional appearance in engine bays, fuel systems, and custom hydraulic installations.

Constructed from aluminum, this reducer weighs only 0.08 lbs and measures 2.8 x 1.15 x 3.8 inches, making it compact enough for tight installations without adding significant bulk. The male-to-male configuration allows direct connection between 8 AN female ports and 6 AN female fittings, maintaining system integrity while simplifying plumbing architectures. AN (Army Navy) standard fittings are the industry baseline for high-pressure fuel, coolant, and hydraulic systems in motorsports, street performance vehicles, and marine applications where reliability under pressure is non-negotiable.

This adapter is commonly used in custom fuel system builds, engine conversions, and aftermarket cooling upgrades where OEM line sizes don't align with available components. Builders working with LS swaps, turbo installations, or full fuel system replumbing rely on adapters like this to eliminate unnecessary hose runs and reduce potential leak points. The straight-pattern design ensures minimal turbulence and pressure loss compared to angled alternatives, critical when optimizing fuel delivery to high-flow carburetors or EFI systems.

AN fittings remain the gold standard across performance automotive, aviation, and industrial hydraulics because of their reusable design, consistent thread specs, and ability to handle sustained high-pressure cycles. Whether you're assembling a precision fuel system or adapting an existing line configuration, REDHORSE Performance adapters maintain the reputation for precision machining and durability that the brand has built in the aftermarket performance sector.
