AN to NPT Straight #10 x 3/8

The Triple X Race Components AN to NPT Straight #10 x 3/8 adapter is a precision hydraulic and fuel line fitting designed to bridge two industry-standard port types in high-performance motorsports, automotive, and aerospace applications. This straight adapter connects a -10 AN (JIC 37-degree flare) male port to a 3/8-inch NPT (National Pipe Taper) male port, making it essential for fuel system plumbing, coolant lines, and brake system configurations where existing manifolds or components use different thread standards.

Constructed from aluminum and finished in black anodized coating, this fitting delivers corrosion resistance and lightweight performance critical in salt-air environments, high-vibration engine bays, and race car applications. The anodized finish provides additional durability against fuel, oil, and coolant exposure while maintaining a professional appearance. At 0.06 lbs and compact 2.25 x 1.2 x 3.55-inch dimensions, the adapter integrates seamlessly into tight spaces without adding significant weight—a priority in motorsports builds where every fraction counts. The straight geometry (no 45 or 90-degree angle) simplifies installation and minimizes turbulence in fluid delivery systems where flow efficiency matters.

This fitting serves race car builders, restoration shops, fuel system engineers, and performance enthusiasts standardizing mixed-port manifold configurations. Whether you're converting a vintage engine bay to modern fuel injection, integrating aftermarket fuel rails with OEM block ports, or plumbing custom hydraulic systems, this AN to NPT adapter eliminates costly manifold modifications. The combination of -10 AN male and 3/8 NPT male threads matches common block-mounted fuel rail ports and aftermarket adapter bundles found in street performance and circle-track racing setups.
