6AN PTFE Hose Ends Blue 90

The 6AN PTFE Hose Ends Blue 90 from REDHORSE PERFORMANCE are precision-engineered fittings designed for high-performance fuel, coolant, and brake line applications in street, strip, and track vehicles. These 90-degree elbow adapters serve as the critical connection point between flexible braided hoses and rigid fuel rails, carburetors, fuel pumps, and manifold ports. Whether you're building a classic hot rod fuel system, upgrading a modern performance engine bay, or fabricating a custom cooling loop, reliable hose ends are non-negotiable for safety and system integrity.

REDHORSE's 6AN PTFE construction combines aerospace-grade PTFE (polytetrafluoroethylene) core tubing with premium aluminum or steel body construction, delivering superior heat resistance and chemical compatibility compared to standard rubber hoses. The blue anodized finish provides both aesthetic appeal and corrosion protection in engine compartments exposed to salt spray, fuel vapors, and thermal cycling. The 90-degree configuration eliminates bulky mandrel bends, reduces dead spots in fuel lines, and simplifies tight-fit installations around intake manifolds and firewall passages. PTFE inner liners prevent fuel permeation, ensuring consistent pressure and zero weeping at the molecular level—critical when running ethanol blends or high-octane race fuel.

Mechanics and fabricators trust 6AN PTFE hose ends for forced-induction platforms, carbureted engines, and EFI conversions requiring SAE J518 port compatibility. The 6AN sizing (3/8-inch nominal ID) accommodates fuel flow rates up to 100+ GPH, making it ideal for high-output builds, turbo applications, and dual-fuel systems. Installation requires standard hose crimpers and AN adapter fittings; verify your fuel rail, carburetor port, and pump outlet threads before ordering to ensure seamless integration. Stock these blue 90-degree ends as spares during engine rebuilds or keep them on hand for custom plumbing modifications.
