AN To NPT Straight -8 x 1/2in

The ALLSTAR PERFORMANCE AN to NPT Straight -8 x 1/2in adapter is a crucial fitting for high-performance fuel and fluid systems in custom automotive builds. This adapter bridges two critical industry-standard thread formats—AN (Army Navy) and NPT (National Pipe Tapered)—allowing seamless integration between modern performance components and legacy or OEM infrastructure.

The -8 designation refers to the AN hose size, which has a nominal inner diameter of 1/2 inch. The 1/2 inch NPT port accommodates standard threaded connections on fuel rails, gauges, filters, and manifold ports. The straight orientation minimizes turbulence and restricts loss during fuel delivery, which is critical for carbureted engines, EFI systems, and pressurized cooling applications.

Mechanics and fabricators routinely use this adapter when converting older carbureted platforms to modern fuel injection, installing aftermarket fuel pressure regulators, or building custom engine bay plumbing. ALLSTAR PERFORMANCE maintains tight tolerances and uses quality materials throughout their adapter line, ensuring durability through thermal cycling and pressure fluctuations typical in modified engines.
