AN To NPT 90 Degree -4 x 1/4in

The AN To NPT 90 Degree -4 x 1/4in adapter by Allstar Performance is a crucial component for fluid routing in high-performance and modified vehicles. This right-angle adapter connects AN (Army-Navy) threaded fittings to NPT (National Pipe Thread) ports, making it ideal for technicians and enthusiasts working on custom fuel, oil, coolant, and brake systems.

Designed to facilitate smooth hose routing, the 90-degree elbow geometry minimizes sharp bends in braided hose runs, reducing stress on fittings during thermal cycling and vibration. The -4 AN port accommodates standard -4 braided hose, while the 1/4-inch NPT female port is compatible with common industrial and automotive NPT-threaded components.

This adapter is particularly beneficial for engine builders, performance shops, and DIY enthusiasts looking to integrate modern braided hose systems with factory or aftermarket NPT-ported components. Its design allows for clean routing around engine components, pulleys, and frame rails, ensuring system integrity and optimal flow rates.
