3AN to 2AN(1/8)NPT Adapter 45

The 3AN to 2AN(1/8)NPT Adapter 45 by REDHORSE PERFORMANCE is a precision-engineered hydraulic and fuel line fitting designed for custom automotive, racing, and high-performance applications. This 45-degree adapter bridges AN (Army-Navy) flange connections to NPT (National Pipe Thread) ports, making it essential for integrating modern aftermarket components with legacy equipment or OEM systems that use different thread standards. Whether you're building a custom fuel system, upgrading brake lines, or connecting hydraulic circuits in a race vehicle, this adapter eliminates the need for costly custom fabrication.

Constructed from aluminum and finished in black anodized coating, the 3AN to 2AN(1/8)NPT Adapter 45 provides corrosion resistance and a professional appearance in engine bays and fuel cell enclosures. The 45-degree angle orientation allows flexible routing in tight spaces where straight adapters would create clearance conflicts, while the aluminum construction keeps system weight low—critical in performance and racing environments where every pound matters. The NPT male threads create a reliable, sealed connection that resists vibration and thermal cycling, and the AN male connection accepts standard hose fittings with proven reliability in high-pressure applications.

This fitting is ideal for fuel system upgrades, engine conversions, and custom builds where port configurations don't align with off-the-shelf solutions. It's commonly used in street rods, drag racing fuel systems, performance boat engines, and industrial hydraulic applications. Installation requires no special tools—simply thread the NPT end into a compatible NPT port and connect your AN hose assembly to the male AN end. The compact 2.75-inch length and lightweight 0.06-pound profile make it easy to route and install in congested engine compartments without adding significant bulk to your fuel or hydraulic system.
