When it comes to custom plumbing systems, especially in high-performance vehicles or machinery, choosing the right fittings is crucial for ensuring durability and functionality. One commonly used component in such systems is the 20 AN Fittings Female 90, a type of fitting designed to connect hoses and pipes in an angled configuration. In this article, we will explore what 20 an fittings female 90 are, their applications, and why they are so important for performance and reliability.

Understanding AN Fittings

AN fittings are a type of connector used primarily in the automotive, aerospace, and racing industries. The term “AN” stands for Army-Navy, which comes from military specifications for fluid and air transfer systems. These fittings use a standardized thread size, ensuring compatibility across a variety of hoses and components.

The AN size system is measured by the outer diameter of the hose or pipe in sixteenths of an inch. For example, a 20 AN fitting corresponds to a 20/16-inch (1.25-inch) outer diameter. These fittings are known for their high strength, corrosion resistance, and reliability, making them ideal for high-pressure applications.

What is a 20 AN Female 90 Fitting?

A 20 AN Female 90 Fitting refers to a specific type of connector that features:

• 20 AN Size: The fitting is designed to fit a 1.25-inch (20/16-inch) hose or pipe.
• Female Thread: The fitting has internal threads that allow it to screw onto male-threaded fittings, hoses, or other components.
• 90-Degree Angle: The fitting is bent at a 90-degree angle, making it ideal for tight spaces where hoses or pipes need to change direction.

The “Female” part of the name indicates that the fitting has internal threads, and it’s used to connect to male-threaded components. The 90-degree angle allows for easy routing of fluid lines in confined areas, offering a more efficient, clean installation. These fittings are available in various materials, including aluminum, steel, and stainless steel, depending on the application requirements.

Applications of 20 AN Female 90 Fittings

20 AN Female 90 fittings are commonly used in a wide range of applications, particularly where flexibility and durability are paramount. Some key industries and scenarios include:

1. Automotive Performance: In racing and performance vehicles, 20 AN fittings are used to connect fuel lines, oil lines, and coolant systems. The 90-degree angle allows for smooth routing around tight engine compartments without excessive bending, preventing kinks or flow restrictions.

2. Aerospace: In aerospace engineering, where space and weight constraints are critical, these fittings are often used to connect hydraulic lines or fuel lines. The corrosion resistance of high-quality materials ensures safety and longevity under extreme conditions.

3. Marine Systems: Marine vessels, especially racing boats, use these fittings to handle high-pressure fuel and oil systems. The 90-degree bend makes it easier to route fluid lines around obstacles on the boat’s engine or mechanical components.

4. Custom Plumbing Systems: In custom builds, including those for motorsports, off-road vehicles, or experimental machinery, 20 AN Female 90 fittings provide the flexibility needed to navigate complex plumbing systems, whether it’s for fuel, coolant, or hydraulic fluid.

Why Choose 20 AN Female 90 Fittings?

There are several reasons why the 20 AN Female 90 fitting is a popular choice for professionals and hobbyists alike:

• Space Efficiency: The 90-degree angle makes it possible to route hoses and pipes efficiently in compact spaces, reducing clutter and improving airflow in systems.

• Durability: High-quality materials like stainless steel and anodized aluminum are corrosion-resistant and can withstand high pressure, making these fittings suitable for both everyday and extreme applications.

• Versatility: Whether you're working on a car, boat, or aircraft, 20 AN Female 90 fittings are compatible with a variety of hoses and tubes, making them versatile in different setups.

• Ease of Installation: These fittings are designed for easy installation with standard wrenches or torque tools, simplifying maintenance and replacements.

Conclusion

In the world of high-performance vehicles, racing, and custom plumbing systems, 20 AN Female 90 fittings provide an essential function: connecting hoses and pipes at a right angle with reliability and strength. With their compact design, durability, and versatility, these fittings are perfect for a variety of industries, from automotive to aerospace to marine applications. When building or upgrading a performance system, using the right fittings like the 20 AN Female 90 can make all the difference in ensuring long-lasting functionality and safety.
