AN to NPT Straight #16 x 3/4

The AN to NPT Straight #16 x 3/4 adapter from Triple X Race Components is a precision hydraulic and fuel system fitting designed to bridge two industry-standard thread types in high-performance and motorsport applications. This straight adapter connects 16 AN (Army-Navy) male ports to 3/4 inch NPT (National Pipe Thread) male ports, making it essential for custom fuel lines, coolant systems, and hydraulic assemblies where existing components use different port standards. Built for reliability in demanding environments, this fitting eliminates the need for costly component replacement when integrating legacy or specialized equipment.

Machined from aluminum and finished in black anodized coating, the AN to NPT Straight #16 x 3/4 offers corrosion resistance and a professional appearance while maintaining lightweight properties critical for race and performance builds. The black anodize protects the aluminum substrate against oxidation and minor abrasion, extending service life in engine bays and underbody installations. The straight configuration (as opposed to 90-degree or 45-degree variants) allows for direct in-line connections where space permits, simplifying plumbing layouts and reducing fitting count in complex fuel and coolant systems.

This adapter is ideal for fabricators, race teams, and automotive enthusiasts building custom fuel delivery, intercooler, or hydraulic systems that must integrate older NPT-threaded components with modern AN hose standards. Common applications include fuel cell installations, turbo charge-air piping, transmission cooler lines, and brake system modifications where NPT ports on industrial or legacy pumps and valves require connection to AN hoses. The compact 2.7 x 1.55 x 3.55 inch profile and minimal 0.11 lb weight ensure easy routing and mounting in confined engine compartments without adding significant mass.
