Reducer AN Male -6 to -10

The Reducer AN Male -6 to -10 from ALLSTAR PERFORMANCE is a precision hydraulic and pneumatic adapter fitting designed to connect larger -10 AN (10/16") port systems to smaller -6 AN (6/16") components. This straight reducer serves high-performance applications where fluid lines, fuel systems, or air lines require step-down coupling without additional complexity. Whether you're building a custom cooling loop, fuel delivery system, or pneumatic circuit, this adapter eliminates the need for multiple fittings or external reducers.

Constructed from aluminum and finished in black anodized coating, the Reducer AN Male -6 to -10 provides corrosion resistance and a professional appearance while maintaining lightweight durability. The anodized surface protects against oxidation in demanding environments and resists fluid degradation over time. The straight-flow design minimizes turbulence and pressure drop compared to elbow or tee configurations, making it ideal for applications where flow efficiency matters. Weighing just 0.07 lbs, this compact fitting integrates seamlessly into tight engine bays, chassis enclosures, or control panel layouts without adding bulk.

This adapter benefits fabricators, hot rod builders, race teams, and industrial technicians who demand reliable stepped transitions in fluid systems. Installation requires basic wrench work—simply thread the male ends into corresponding female AN ports using appropriate sealant (PTFE tape or pipe dope). The -6 to -10 sizing works across fuel injection systems, transmission coolers, oil circuits, and pneumatic air tools. Compatible with any system using standard AN metric threads, this reducer ensures consistent flow from larger supply lines to smaller component inlets, reducing the risk of cavitation and maintaining system integrity across temperature and pressure cycling.
