AN to NPT Straight #8 x 1/2

The TRIPLE X RACE COMPONENTS AN to NPT Straight #8 x 1/2 adapter is a precision hydraulic fitting designed for high-performance racing and fuel system applications. This straight adapter transitions an 8 AN male connection to a 1/2-inch NPT male port, enabling seamless integration between AN-spec hose systems and NPT-threaded components. Manufactured from aluminum and finished in black anodized coating, this fitting delivers reliable sealing and corrosion resistance in demanding engine bay and fuel system environments.

The 8 AN designation refers to the hose size in sixteenths of an inch (8/16" or 1/2"), a standard used throughout motorsports and performance automotive applications. The NPT (National Pipe Thread) side accommodates factory or aftermarket fuel rails, carburetors, and gauge ports. Aluminum construction keeps weight minimal—critical in race vehicles where every fraction of a pound matters—while black anodized finish provides UV resistance and aesthetic consistency with modern engine builds. The straight configuration allows direct port alignment without angular offset, simplifying installation in tight engine compartments.

This adapter is essential for builders transitioning vintage fuel systems to modern AN plumbing standards, converting mechanical fuel pressure gauges to AN hose distribution, or adapting aftermarket fuel injection rails to existing NPT-threaded fuel blocks. Drag racers, circle track competitors, and street performance enthusiasts regularly use TRIPLE X fittings to ensure leak-free connections under sustained high pressure and temperature cycling. The NPT thread form creates a mechanical seal through thread deformation, making this fitting suitable for both fuel and coolant applications where reliability cannot be compromised.
