AN To NPT Straight -10 x 3/4in

The ALLSTAR PERFORMANCE AN to NPT Straight -10 x 3/4in adapter (ALL 49519) is a critical hydraulic and fuel system fitting designed to bridge two industry-standard thread types in high-pressure applications. This AN to NPT straight adapter converts a -10 AN (JIC) male connection to a 3/4 inch NPT male thread, enabling seamless integration between systems that use different fastening standards. Manufactured from aluminum and finished in black anodized coating, this fitting delivers corrosion resistance and durability in demanding environments.

The -10 AN size corresponds to 5/8-inch outside diameter tubing in the AN/JIC standard, a specification widely used in motorsports fuel delivery systems, racing hydraulics, and performance engine builds where precise, leak-free connections are essential. NPT (National Pipe Thread) remains the dominant standard in industrial hydraulic applications, making this adapter invaluable for technicians bridging legacy systems or custom installations. The straight configuration—as opposed to 90-degree or 45-degree variants—simplifies plumbing layouts and minimizes flow disruption. Black anodizing provides enhanced corrosion resistance compared to bare aluminum, particularly important in salt-air environments or systems exposed to moisture.

This fitting serves shops and builders working on custom fuel systems, forced induction installations, and racing hydraulic setups where adapter compatibility is non-negotiable. Whether upgrading a carbureted engine to EFI plumbing or integrating aftermarket cooling systems with existing NPT ports, this AN to NPT adapter provides the precise interface required. The lightweight aluminum construction—0.11 lbs—adds minimal weight while maintaining pressure-rated integrity. Technicians and fabricators rely on ALLSTAR PERFORMANCE fittings for consistent fitment and trusted performance across thousands of builds.
