What Are AN Fittings
What Are AN Fittings
When it comes to fuel delivery systems, the importance of reliable and efficient connections cannot be overstated. AN (Army-Navy) fittings, originally designed for military applications, have become a cornerstone of modern automotive and racing industries. These precision-engineered fittings offer robust connections for an fittings for fuel lines, ensuring safety, performance, and durability.
What Are AN Fittings?
AN fittings are high-performance connectors used in fuel lines, oil lines, brake lines, and other fluid transfer systems in vehicles. They are renowned for their leak-proof design, compatibility with high-pressure systems, and adaptability to various automotive applications.
The fittings are named using a numerical sizing system (e.g., AN-6, AN-8), where the number corresponds to the outside diameter of the tubing in sixteenths of an inch. For example, an AN-6 fitting works with 3/8-inch tubing.
Features of AN Fittings for Fuel Lines
-
Precision Design:
AN fittings feature a 37-degree flare design, ensuring a secure and leak-free seal. This design is critical for high-pressure fuel delivery systems, where even a minor leak could result in performance issues or safety hazards. -
Material Options:
Most AN fittings are made from lightweight, corrosion-resistant materials like aluminum or stainless steel. Aluminum fittings are common in racing due to their low weight, while stainless steel is preferred for its durability and resistance to harsh chemicals. -
Versatility:
AN fittings come in a wide variety of shapes and configurations, including straight, 45-degree, and 90-degree angles, allowing for flexible routing of fuel lines in tight engine bays. -
Compatibility:
These fittings are designed to work with a wide range of hose types, including braided stainless steel hoses and PTFE (polytetrafluoroethylene) hoses, which are highly resistant to fuel, heat, and pressure.
Advantages of Using AN Fittings for Fuel Lines
-
Leak Prevention:
The 37-degree flare and robust threaded connections create a tight seal, preventing fuel leaks that could lead to engine malfunctions or fire hazards. -
High-Pressure Tolerance:
AN fittings are capable of handling the high pressures found in modern fuel injection systems, making them ideal for performance vehicles. -
Customizability:
With a range of sizes, materials, and configurations, AN fittings allow for fully customized fuel line setups, accommodating unique vehicle layouts and performance needs. -
Durability:
Built to withstand extreme temperatures, vibrations, and exposure to fuels and oils, AN fittings are a long-lasting solution for demanding automotive applications.
Installation Tips for AN Fittings
-
Select the Right Size:
Ensure that the fitting size matches the fuel line diameter for a proper fit and optimal flow. -
Use Quality Tools:
Invest in AN-specific wrenches to avoid damaging the fittings during installation. -
Inspect for Damage:
Check the fitting and hose for any cracks, dents, or debris that could compromise the connection. -
Proper Assembly:
Follow manufacturer guidelines when assembling the fitting and hose. PTFE hoses, for instance, require precise cutting and seating for a secure connection.
Applications of AN Fittings
While AN fittings are most commonly associated with fuel lines, they are also used in oil lines, coolant systems, brake lines, and turbocharger setups. Their versatility and reliability make them a popular choice for automotive enthusiasts, race teams, and high-performance vehicle manufacturers.
