Hose Fitting #16 45 Deg. to #12 Hose Black

The Hose Fitting #16 45 Deg. to #12 Hose Black (SKU: FRG224515-BL) from FRAGOLA is a precision adapter engineered for high-performance fuel, coolant, and hydraulic systems in modified vehicles. This 45-degree AN hose fitting bridges different port sizes—critical when routing fuel lines, intercooler connections, or brake systems in tight engine bays where space and pressure integrity demand professional-grade components. Built for street performance, racing, and custom fabrication, this fitting eliminates the need for multiple adapters and reduces potential leak points in your cooling or fuel delivery system.

Machined from aluminum and finished in black anodizing, the Hose Fitting #16 45 Deg. to #12 Hose Black provides corrosion resistance and a clean appearance under the hood. The 45-degree geometry allows flexible routing around engine components, intake manifolds, and turbochargers without stress on hose terminations—a critical design feature that extends line life and prevents fatigue cracking. FRAGOLA's 2000 Series Pro-Flow construction ensures smooth internal passages that minimize turbulence and pressure drop, maintaining optimal flow rates whether you're running stock boost or upgraded fuel system demand on a carbureted, EFI, or twin-turbo setup.

This adapter pairs a #16 AN female port with a #12 AN hose connection, making it ideal for fuel system manifolds, regulator outlets, or distribution blocks feeding smaller diameter braided hose runs. Mechanics and fabricators rely on FRAGOLA fittings for consistency across custom fuel injection conversions, carburetor upgrades, and high-flow coolant loops on LS swaps and other engine platform changes. The compact 5.35-inch length fits snugly in congested engine compartments, and the anodized finish resists weeping around connection threads when properly torqued to specification.
