What are AN fittings?

AN fittings, also known as Army-Navy fittings, are a type of fitting used in high-performance automotive and racing applications. They are designed to provide a secure, leak-free connection for fuel, oil, and other fluid systems, and are popular among car enthusiasts for their strength, durability, and versatility.

One of the main advantages of AN fittings is their ability to handle high pressures and temperatures. They are typically made from aluminum or steel, which are strong and lightweight materials that can withstand the high pressures and temperatures found in high-performance engines. Additionally, AN fittings are designed to be reusable, which means they can be disconnected and reconnected multiple times without losing their seal.

Another advantage of AN fittings is their versatility. They come in a variety of sizes and styles, which allows them to be used in a wide range of applications. For example, they are commonly used in fuel systems, oil systems, brake systems, and intercooler systems. They can also be used to connect hoses, lines, and other components together.

When it comes to selecting AN fittings, the first thing to consider is the size of the fitting. AN fittings are available in a range of sizes, from -4 to -20, with -4 being the smallest and -20 being the largest. The size of the fitting you choose will depend on the size of the hose or line you are using, as well as the pressure and flow rate of the fluid you are working with.

Another important factor to consider when selecting AN fittings is the type of fitting. There are a few different types of AN fittings available, including straight, elbow, and tee fittings. Straight fittings are used to connect two hoses or lines together, while elbow fittings are used to change the direction of a hose or line. Tee fittings are used to split a line into two or more lines.

Lastly, it’s important to consider the material of the fitting. AN fittings are commonly made from aluminum or steel. Aluminum fittings are lightweight, corrosion-resistant, and suitable for most applications. Steel fittings are stronger and more durable, and are typically used in high-pressure and high-temperature applications.

In conclusion, AN fittings are a popular choice among car enthusiasts and racers for their strength, durability, and versatility. They are designed to handle high pressures and temperatures, and come in a variety of sizes, styles, and materials. When selecting AN fittings, it is important to consider the size, type, and material of the fitting to ensure that it is suitable for your application.
