AN To NPT 45 Degree -10 x 1/2in

The AN to NPT 45 degree -10 x 1/2in adapter from ALLSTAR PERFORMANCE (SKU ALL 49548) is a precision hydraulic and fuel system fitting designed for applications requiring fluid line transitions between AN (Army-Navy) and NPT (National Pipe Thread) connections. This adapter is essential for builders, mechanics, and enthusiasts who need to convert between two industry-standard thread types while maintaining a 45-degree angle orientation. Whether you're assembling a custom fuel system, upgrading cooling lines, or integrating aftermarket components into existing infrastructure, this adapter provides a reliable, leak-free solution for cross-platform compatibility.

Constructed from aluminum and finished in black anodized coating, this fitting combines lightweight durability with corrosion resistance—critical for long-term reliability in demanding environments. The 45-degree angle design reduces stress on connected hoses and components by allowing natural flow direction changes without sharp bends or kinks that could compromise pressure integrity. The -10 AN male end accommodates standard -10 hose sizing, while the 1/2-inch NPT male thread integrates with conventional pipe-threaded ports found on engines, reservoirs, and OEM hydraulic systems. Black anodizing provides both aesthetic consistency and protective oxidation that prevents galvanic corrosion when paired with various metals.

This adapter suits custom automotive builders, motorsports applications, industrial hydraulic assembly, and any situation where AN quick-disconnect fittings must interface with NPT-threaded ports. Installation is straightforward: apply appropriate thread sealant to the NPT end, thread into the receiving port, and secure the AN hose using a standard -10 hose fitting. Weighing just 0.1 pounds, it adds negligible weight while serving as a critical compatibility bridge. Proper installation ensures zero seepage and sustained pressure ratings suitable for fuel delivery, brake lines, and coolant circulation systems.
