8an Male 90-Deg Flare Adapter Fitting Blue

The 8AN Male 90-Deg Flare Adapter Fitting Blue by REDHORSE PERFORMANCE is an essential component for high-flow fuel, oil, and coolant line routing in performance engine builds and custom automotive projects. Whether you're upgrading a fuel system, installing a turbo cooler, or routing braided hose lines through a tight engine bay, this 90-degree adapter lets you change direction without kinking or restricting flow. Professional mechanics and serious enthusiasts rely on quality flare fittings to eliminate leaks, maintain system integrity under boost, and ensure clean, professional-looking plumbing in show-quality builds.

Built by REDHORSE PERFORMANCE—a trusted name in motorsport plumbing—this 8AN male fitting features a 90-degree elbow geometry that allows hose runs to navigate around engine components, chassis members, and ancillaries without introducing dead zones or turbulent flow patterns. The flare design (AN standard double-flare) creates a metal-to-metal seal that handles sustained pressure in fuel injection systems, boosted cooling circuits, and pressurized oil lines. Anodized blue finish resists oxidation, improves visibility for system identification, and adds visual appeal to engine bay aesthetics while the precision-engineered cone angle ensures consistent, leak-free connections across multiple cycles and temperature ranges.

This adapter is ideal for street machines, track cars, and performance truck builds where custom fuel cell installation, auxiliary cooling systems, or turbo setups demand flexible routing options. The 8AN size handles fuel flow rates up to approximately 120+ GPH, making it suitable for carbureted builds, EFI systems, and moderate forced-induction applications. Installation requires compatible 8AN hose and female fittings; ensure proper flare fitting seat cleanliness and use threadlocker on connections subject to vibration. Available for immediate purchase online, this compact fitting (3.8 x 1 x 5.2 in) integrates seamlessly into tight engine bays and custom fuel cell configurations.
