Hose Fitting #8 45 Deg. to #6 Hose Black

The Hose Fitting #8 45 Deg. to #6 Hose Black is an essential step-down adapter for automotive fuel, coolant, and hydraulic systems where line-size transitions are critical. Designed for performance builds and precision fuel system plumbing, this 45-degree AN fitting bridges an 8 AN female port to a 6 AN hose, allowing builders to optimize hose routing in tight engine bays and custom installations. Whether you're upgrading a fuel delivery system, fabricating a custom cooling loop, or integrating aftermarket fuel injection hardware, this adapter ensures secure connections without requiring expensive manifold modifications.

Manufactured by FRAGOLA under their 2000 Series Pro-Flow line, this fitting is forged from lightweight aluminum and finished in black anodized coating for corrosion resistance and a clean OEM appearance in engine compartments. The 45-degree angle design allows hose runs to navigate around engine accessories, transmission mounts, and suspension components without kinking or stress concentration at the fitting. AN (Army/Navy) sizing is industry-standard in performance motorsports, with the #8 and #6 designations referring to internal hose diameter standards—this adapter's precise machining ensures a reliable seal with standard -8 and -6 hose sizes when paired with compatible compression-style fittings and hoses.

Engine builders, fuel system fabricators, and track-focused enthusiasts rely on step-down fittings like this to consolidate line sizes in fuel systems, coolant circuits, and brake fluid plumbing. The black anodized finish integrates seamlessly into modern engine bay aesthetics, and the compact 45-degree profile (2.15 x 1.4 x 4.35 inches) minimizes bend radius requirements for tight installations. Pair this fitting with Pro-Flow hose assemblies, clamps, and complementary AN adapters to build a leak-free, professional-grade fuel or cooling system that meets both street and racing standards.
