3AN Female to 3AN Male 90Deg Clear

The 3AN Female to 3AN Male 90Deg Clear fitting from REDHORSE PERFORMANCE is an essential adapter for custom fuel, coolant, and hydraulic systems in modified vehicles. Built for high-performance fuel injection, turbo cooling, and precision brake line applications, this 90-degree AN adapter allows you to change line direction without kinking or restricting flow. Whether you're building a custom engine bay, installing a fuel surge tank, or routing cooler lines around tight engine compartments, this fitting enables the flexible routing modern vehicle modifications demand.

This adapter features a clear anodized aluminum construction, which provides corrosion resistance while allowing you to visually inspect fluid condition in-line—critical when troubleshooting fuel quality or coolant clarity on high-boost applications. The 90-degree angle design reduces stress concentration at connection points compared to flexible hose bends, improving durability under vibration and thermal cycling common in forced-induction and high-output builds. Both ends are 3AN-sized (3/16-inch) with female and male JIC flare threads, ensuring leak-free sealing at system pressures up to typical fuel injection and cooling system specifications when properly torqued.

This adapter is ideal for mechanics and enthusiasts assembling fuel cell systems, intercooler circuits, and remote-mounted reservoir configurations where space is tight and precise line routing is non-negotiable. The lightweight design (0.055 lbs) won't stress mounting brackets, and the compact 90-degree profile fits where 45-degree fittings fall short. Install using a wrench or AN hose wrench on both the adapter body and the mating connector to prevent thread stripping—this fitting works seamlessly with any SAE J518 Code 61 (JIC flare) hose or adapter in your system.
