6AN to 2AN(1/8)NPT Union Adapter 90

The 6AN to 2AN (1/8) NPT Union Adapter 90 from REDHORSE PERFORMANCE is an essential fitting for custom fuel, oil, and coolant line systems in performance and modified vehicles. This 90-degree union adapter bridges mismatched port sizes and thread types, allowing mechanics and enthusiasts to integrate AN (Army-Navy) fittings with NPT (National Pipe Thread) components—a common requirement when upgrading fuel injection systems, turbocharger installations, or building custom engine cooling circuits.

Constructed from durable aluminum alloy with precision-machined internal passages, the 6AN to 2AN (1/8) NPT Union Adapter 90 features a 90-degree elbow design that optimizes space in tight engine bays and manifold areas while maintaining full flow capacity. The 6AN side accepts standard -6 AN hose fittings, which typically correspond to a 3/8-inch inner diameter hose, while the 2AN (1/8) NPT port threads directly into factory or aftermarket receivers without additional adapters.

This adapter is ideal for EFI conversions, fuel cell installations, turbo kit integrations, and adapting aftermarket components, ensuring reliable and aesthetically pleasing connections. REDHORSE PERFORMANCE's tight tolerances help ensure leak-free connections and corrosion resistance in both hot engine compartments and fuel tank environments, critical for long-term reliability in modified applications.
