16AN STR Male Adapter 1in NPT Male Blue

The 16AN STR Male Adapter 1in NPT Male Blue is a precision hydraulic and pneumatic fitting designed to bridge AN (Army-Navy) and NPT (National Pipe Thread) connection standards. This straight adapter is essential for fuel systems, coolant lines, pneumatic applications, and industrial fluid transfer where direct port connection between different threading standards is required. Whether you're building a custom fuel system, restoring a classic vehicle, or establishing industrial equipment connections, this adapter eliminates the need for improvised solutions and ensures leak-free, reliable performance.

Manufactured by REDHORSE PERFORMANCE, a trusted name in high-performance fluid transfer systems, this fitting features a 16 AN male connection on one end and a 1-inch NPT male connection on the other, both precision-machined for exact sizing and compatibility. The body is constructed from lightweight yet durable aluminum and finished in blue anodized coating, which provides superior corrosion resistance, UV stability, and visual identification of the fitting type. The straight (STR) design minimizes turbulence and pressure drop, making it suitable for applications requiring consistent flow rates and maximum system efficiency.

This adapter is ideal for automotive enthusiasts, fabricators, and technicians working with aftermarket fuel injection systems, turbocharger installations, custom cooling loops, and pneumatic machinery. The compact profile (measuring 2.8 x 1.4 x 3.75 inches) allows for flexible installation in tight engine bays and equipment housings. Compatible with any system using standard 16 AN hose fittings and 1-inch NPT ports, this fitting delivers the reliability and precision expected from professional-grade performance components. Proper thread sealant is recommended for NPT connections to ensure maximum leak prevention in high-pressure applications.
