16AN 90Deg Male Adapter to 1in NPT Male Black

The 16AN 90Deg Male Adapter to 1in NPT Male Black from REDHORSE PERFORMANCE is a precision-engineered hydraulic adapter designed for high-performance fuel systems, coolant circuits, and custom plumbing applications in modified vehicles. This adapter serves as a critical bridge component in custom engine builds, turbo installations, and fuel injection system upgrades where AN (Army-Navy) standard fittings must interface with National Pipe Thread (NPT) ports commonly found on factory engine blocks, transmission coolers, and aftermarket manifolds.

Manufactured from durable aluminum alloy and finished in black for corrosion resistance, this adapter features a 16AN port on one end and a 1-inch NPT male thread on the opposite end, allowing directional flexibility during tight under-hood routing. The 90-degree elbow configuration eliminates sharp bends in hose lines, reducing stress concentration and improving fluid flow dynamics compared to sequential adapters.

This adapter is essential for builders integrating aftermarket fuel systems and installing custom boost circuits that may operate at pressures exceeding 100 PSI. Mechanics and enthusiasts rely on this adapter to create reliable, leak-free connections in demanding performance environments, ensuring optimal performance in their modified vehicles.
