Hose Fitting #10 45 Deg. to #12 Hose Black

The Hose Fitting #10 45 Deg. to #12 Hose Black from FRAGOLA is a precision adapter designed for custom fuel system routing and high-performance hydraulic applications where space constraints or complex plumbing layouts demand angled transitions between different hose sizes. This 45-degree fitting serves as a critical junction point for builders who need to redirect flow while maintaining compact clearance around engine bay obstacles, suspension components, or frame rails. Whether you're building a fuel-injected swap, designing a custom cooling circuit, or integrating a high-pressure brake or power steering upgrade, this adapter eliminates the need for bulky elbows or multiple straight fittings that consume valuable real estate.

Manufactured from aluminum and finished in black anodized coating, the Hose Fitting #10 45 Deg. to #12 Hose Black features FRAGOLA's 2000 Series Pro-Flow design that delivers low-restriction flow paths and repeatable, leak-free connections. The fitting connects a #10 AN female port on one end to a #12 AN hose on the other, allowing you to step up hose sizes while changing direction in a single component—a practical solution that reduces assembly complexity and potential leak points. The 45-degree angle geometry is optimized for automotive installations where 90-degree bends prove impractical; this intermediate angle offers the flexibility professional tuners demand while maintaining structural integrity under pressure cycles and vibration.

Mechanics and fabricators rely on FRAGOLA's 2000 Series fittings for fuel systems, transmission coolers, and brake applications where aluminum construction and anodized protection resist corrosion in underhood environments. This adapter is ideal for street rods, late-model swaps, drag cars, and road-course builds where every millimeter of clearance matters and the visual presentation of factory-black fittings complements modern engine bay aesthetics. Ensure your hose sizes match the fitting ports precisely—#10 AN accommodates hose with a 5/8-inch inner diameter, while #12 AN accepts 3/4-inch ID hose—to guarantee a proper seal and rated pressure performance.
