Hose Fitting #6 Straight to #8 Hose Black

The Hose Fitting #6 Straight to #8 Hose Black from FRAGOLA is purpose-built for high-flow fuel and coolant systems in performance and modified vehicles where AN-rated hydraulic connections demand reliability. This straight adapter bridges two different line sizes—a #6 AN female port to an #8 AN hose—allowing custom plumbing configurations without complex routing or additional adapters. Whether you're building a fuel system for an engine swap, upgrading coolant flow in a turbocharged application, or designing a custom loop for nitrous oxide delivery, this fitting eliminates the need for offset angles while maintaining maximum flow capacity.

Constructed from aerospace-grade aluminum and anodized in black for corrosion resistance and a clean engine bay aesthetic, the Hose Fitting #6 Straight to #8 Hose Black features FRAGOLA's Pro-Flow 2000 Series design engineered for seamless transitions and minimal turbulence. The straight configuration eliminates dead spots where fluid velocity drops, critical when managing fuel pressure consistency or coolant velocity in boost-cooled systems. The #6 female connection accepts standard fittings while the #8 hose end accommodates larger-diameter braided line, creating a stepped transition ideal for systems requiring progressive sizing to reduce pressure drop across the loop.

Mechanics and fabricators rely on this fitting for street machine fuel systems, race-car plumbing, and high-horsepower engine builds where AN fittings are non-negotiable for safety and performance. Installation requires no special tools beyond standard wrenches—the 37-degree flare sealing surface mates precisely with any AN-rated component, delivering leak-free connections under boost, fuel pressure, or sustained high-flow conditions. Weighing just 0.08 lbs and measuring a compact 4.15 inches in length, it integrates seamlessly into tight engine compartments without compromising access or creating sharp angles that stress hose integrity over time.
