What is the color of an AN steel flared-tube fitting?

The color of an AN steel flared-tube fitting is black. This standard coloring helps to identify the type of fitting and its intended use in fluid systems. The black finish on these fittings is typically a protective coating that also provides corrosion resistance, which is essential because these fittings are often used in dynamic environments where they may be subjected to moisture and various chemicals.

In aviation and automotive applications, the identification of fittings and hose systems is critical for safety and maintenance, making the distinct color coding an important feature. The black color signifies that these fittings are specifically designed for certain pressures and fluid types, ensuring consistency and compatibility across various systems. Understanding this coding aids technicians and engineers in easily recognizing the correct components required for proper assembly and operation in fluid systems.
