AN To NPT Straight -6 x 1/8in

The ALLSTAR PERFORMANCE AN to NPT Straight -6 x 1/8in adapter (SKU ALL 49508) is a precision-engineered fitting designed to connect AN (Army-Navy) hydraulic systems to NPT (National Pipe Thread) ports. This straight adapter transitions a -6 AN male connection to a 1/8-inch NPT male port, making it essential for custom hydraulic line routing in high-performance and racing applications where space constraints or port configurations demand a direct, leak-free coupling.

Constructed from aluminum and finished in black anodized coating, this adapter delivers corrosion resistance and durability in demanding environments. The -6 AN designation corresponds to a 3/8-inch outside diameter hose connection, while the 1/8-inch NPT port accommodates smaller gauge plumbing or sensor feeds. The straight configuration eliminates the need for additional elbows or manifold blocks, reducing potential leak points and simplifying installation in tight engine bays or chassis layouts. Weighing just 0.04 lbs, it adds negligible mass while maintaining structural integrity under pressure cycling.

This fitting is widely used in race car cooling systems, fuel delivery circuits, and auxiliary hydraulic setups where AN braided hose lines must interface with NPT-threaded components such as pressure gauges, switches, or manifold ports. It's also common in custom marine and industrial applications requiring reliable transitions between different thread standards. The black anodized finish provides both aesthetic consistency with modern engine bay presentations and functional corrosion protection in salt-air or high-moisture environments.

When sourcing hydraulic adapters, thread compatibility and pressure rating are critical. This straight AN-to-NPT adapter ensures proper sealing when paired with compatible NPT-port components and AN braided hose fittings, reducing the risk of fluid leaks that can compromise cooling efficiency or fuel system reliability during high-demand operation.
