ColorFittings -4 AN to -10 AN ORB Adapter

ColorFittings ORB Adapter Fittings are precision-engineered to connect AN flare fittings to O-Ring Boss (ORB) ports, providing a secure, leak-free solution for fuel, oil, coolant, power steering, and transmission plumbing systems. ORB ports are found on engine blocks, transmissions, power steering pumps, oil coolers, and other OEM components — making these adapters essential for any AN plumbing conversion.

Our AN to ORB Adapters are manufactured to provide a perfect fit and seal when paired with ColorFittings AN fittings, which are specifically engineered for use with E85, ethanol-based fuels, and race fuels. The O-ring face seal design eliminates the need for thread sealant and provides a more reliable, vibration-resistant connection compared to NPT threads. When combined with our nylon or stainless steel braided hose, these adapters deliver reliable performance and clean routing for any high-performance plumbing system.

For best installation results, we strongly recommend using our AN Fitting Assembly Tools, which help prevent fitting damage and ensure proper hose and fitting alignment. Please reference our installation video and fitting guide for proper assembly techniques and torque recommendations.
