Hose Fitting #10 Str. to #8 Hose Black

The Hose Fitting #10 Str. to #8 Hose Black is a critical adapter for high-performance fuel, coolant, and hydraulic systems in modified vehicles. This straight AN fitting bridges the gap between #10 AN female ports and #8 AN hose connections, making it essential for custom fuel rail systems, turbo intercooler plumbing, and brake line upgrades where space constraints or existing component layouts demand mixed fitting sizes. Whether you're building a forced-induction setup or retrofitting an engine bay with aftermarket fuel delivery components, this adapter ensures leak-free connections where standard single-size fittings won't fit.

Constructed from aluminum and finished in black anodized coating, the Hose Fitting #10 Str. to #8 delivers durability against fuel swell and corrosion while maintaining a lightweight profile—critical in performance builds where every pound counts. The straight-flow design minimizes turbulence and pressure drop compared to 45-degree or 90-degree alternatives, preserving fuel pressure stability and reducing stress on your fuel pump and injectors. The black anodized finish provides both aesthetic integration into modern engine bays and protective oxidation that resists corrosion from ethanol-blended fuels, road salt, and engine heat cycling.

This fitting is ideal for DIY fabricators, professional tuners, and street machine builders working with Pro-Flow hose systems and AN-standard plumbing. Installation requires a wrench on both the port and fitting body to prevent thread stripping—use two wrenches and work deliberately, especially on aluminum components. Verify your system pressure rating before installation; most fuel systems operate 35–70 psi, but forced-induction or methanol builds may demand higher-spec components. Weighing just 0.11 lbs, it adds negligible mass while solving real packaging challenges in engine bays where fuel rails, intercooler piping, or custom brake systems demand adapter solutions.
