Hose Fitting #10 Str. to #12 Hose Black

The Hose Fitting #10 Str. to #12 Hose Black (FRAGOLA 220111-BL) is a precision hydraulic adapter engineered for high-performance fuel, coolant, and brake line systems in modified vehicles and racing applications. This straight connector bridges a #10 AN female port to a #12 AN hose, making it essential for custom engine builds, fuel system upgrades, and turbo installations where precise flow routing and leak-free connections are non-negotiable. Whether you're fabricating a fuel rail, intercooler plumbing, or remote oil filter setup, this fitting ensures reliable performance under pressure.

Manufactured from aluminum and finished in black anodize, the FRAGOLA 2000 Series Pro-Flow design provides durability against corrosion while maintaining a lightweight profile critical in competition and street builds. The straight configuration eliminates unnecessary bends, reducing pressure drop and turbulence—important factors when moving fuel or coolant at high flow rates. The -10 to -12 AN step-down sizing allows you to match existing system components or consolidate redundant line diameters, simplifying installation and improving aesthetic presentation in engine bays. Black anodizing not only resists oxidation but also hides minor cosmetic imperfections common in engine bay environments.

This adapter is ideal for fabricators, tuners, and DIY enthusiasts building custom fuel systems, cooler circuits, or vacuum-assist brake upgrades on LS, small-block Chevy, Ford EcoBoost, and other high-output platforms. Weighing just 0.16 lbs, it integrates seamlessly into tight engine compartments without adding measurable mass. FRAGOLA fittings are trusted across motorsports for their consistent quality and reliable performance at pressure—suitable for both street and track duty. Verify your existing line diameters and system pressure rating before installation to ensure proper fit and safety.
