AN To NPT 90 Degree -10 x 3/4in

The AN to NPT 90 Degree -10 x 3/4in adapter from ALLSTAR PERFORMANCE is a precision fluid-line connector designed for applications requiring a 90-degree directional change. This fitting bridges AN (Army-Navy) male threads to NPT (National Pipe Thread) male ports, making it essential for custom fluid routing in performance engines and racing applications.

Constructed from aluminum and finished in black anodize, this adapter combines lightweight durability with corrosion resistance—critical properties for environments exposed to moisture and thermal cycling. The -10 AN size accommodates substantial flow rates, while the 3/4-inch NPT male thread ensures a secure, leak-free seal when mated to standard NPT ports. The compact design allows for installation in tight spaces, making it ideal for complex plumbing layouts.

Engine builders, performance shops, and automotive enthusiasts will benefit from this fitting when assembling custom fuel delivery systems, turbo coolant lines, and transmission cooler circuits. Installation requires basic thread-sealant application and standard wrenching, ensuring ease of use for both professionals and DIYers alike.
