AN To NPT 45 Degree -6 x 1/4in

The ALLSTAR PERFORMANCE AN to NPT 45 Degree -6 x 1/4in adapter is a vital fitting for hydraulic and pneumatic applications, particularly in custom automotive and engine bay plumbing. This adapter connects AN (Army-Navy) and NPT (National Pipe Taper) thread types, making it ideal for integrating modern performance fuel systems, brake lines, and air suspension setups with existing NPT-threaded components.

Designed with a 45-degree angle, this fitting minimizes turbulence and pressure loss while allowing for flexible hose routing around common obstructions in performance engine bays. The -6 AN thread size corresponds to a 3/8-inch hose ID, and the 1/4-inch NPT connection is suitable for mid-range flow applications. Constructed from durable materials, this adapter is rated for both fuel and hydraulic service, ensuring reliability in demanding conditions.

Ideal for engine swaps and custom fuel systems, this adapter also benefits mechanics and enthusiasts looking to optimize their vehicle's performance. Its angled configuration reduces fitting stress and vibration fatigue, extending the service life of components in vehicles subjected to rigorous use. Whether upgrading a cooling loop or routing custom brake lines, this adapter is a practical solution for enhancing engine compartment layouts.
