Army Navy Fittings: Huge Selection of Valves, Pipes & More!

AN fittings, which stand for Army-Navy, are a specific type of fitting used to securely connect flexible hoses and sometimes metal tubing in various applications. 

Here are key features of AN hose fittings

• High Performance: Originally designed for the demanding aerospace industry, AN fittings are built to withstand high pressure and harsh environments.
• Metal-to-Metal Seal: They use a 37-degree flared design on the hose end that creates a tight, leak-proof seal against the fitting itself. This eliminates the need for additional sealants or tapes.
• Reusable: Unlike some other fitting types, AN fittings can be disassembled and reassembled multiple times without compromising their integrity.
• Lightweight: Typically made from aluminum, AN fittings offer a good balance of strength and weight, making them ideal for performance applications.
• Standardized Sizes: AN fittings come in various sizes designated by an AN hyphen followed by a number (e.g., AN-6, AN-10). This ensures compatibility between fittings and hoses from different manufacturers.

Important Notes:

• AN fittings are not interchangeable with other types of fittings like SAE (Society of Automotive Engineers) fittings, even though they may have similar appearances. The slight difference in flare angles can cause leaks.
• Proper assembly of AN fittings requires specific tools and techniques to ensure a secure and leak-free connection.

AN fittings are used for creating secure, leak-proof connections between flexible hoses and rigid metal tubing that carry fluids. They’re especially popular in applications with high pressure or demanding environments. 

Here’s a breakdown of their key uses:

• High-Performance Vehicles: AN fittings are a common sight in racing cars, performance vehicles, and motorcycles. They can handle the high pressures and vibrations associated with powerful engines.

• Fluid Systems: AN fittings are used in various fluid systems, including fuel lines, oil cooler lines, brake lines, and power steering systems.

• Aerospace Industry: Their origins lie in the aerospace industry, where their tight seals and high durability are crucial.

• Hydraulic Systems: AN fittings find use in hydraulic systems that experience high pressure and require reliable connections to prevent leaks and malfunctions.

Here are some additional points about AN fittings:

• Durability: Made from strong materials like aluminum or stainless steel, they can withstand harsh environments and demanding applications.
• Security: Their design creates a tight, leak-proof seal thanks to the 37-degree flared fitting that forms a metal-to-metal connection.
• Variety: AN fittings come in various sizes (denoted by a dash number system) and configurations (straights, elbows, tees, etc.) to suit different needs.
