8an Female to 10an Male Expander - Black

The 8AN Female to 10AN Male Expander in Black from REDHORSE PERFORMANCE is an essential hydraulic line adapter for custom fuel, coolant, and brake system configurations. This fitting expands from a smaller 8AN port to a larger 10AN connection, making it ideal for high-flow fuel delivery systems, turbo intercoolers, and performance cooling loops where you need to step up hose diameter mid-system.

Engineered from lightweight aluminum, this expander features precision-machined threads and a smooth internal bore to minimize pressure loss and turbulence. The black anodized finish resists corrosion and oxidation, ensuring durability in engine bays exposed to heat cycles, fuel vapors, and moisture. The design maintains structural integrity under boost and sustained high-flow conditions common in performance applications.

Mechanics and engine builders choose this expander when scaling up fuel system capacity for power adders, swapping in larger radiators or intercooler cores, or consolidating multiple smaller lines into a single larger line. The 8AN female port accepts standard -8 AN hoses and fittings, while the 10AN male outlet threads directly into -10 AN female ports on various components.
