AN Fittings in Aviation and Vehicles

AN fitting in aviation is a fitting used to connect hoses, and metal tubing, AN fittings are military-based specifications used in US military aviation applications. It dates back to World War II. The name roots from a standard agreed upon by the US Army and US Navy. The US Army and US Navy are also the origins of the red and blue colours used in the finishing process.

AN fittings meet the performance standards of the aeronautical industry. They carry fluid, and the sizes range from -2 (dash two) to -32 in irregular steps. Each step equates to the OD (outside diameter) of the tubing in ​1⁄16-inch increments.

AN fittings use a 37° flared tubing to form a seal. They are flare fitting and are similar to other 37° flared fittings. They are similar to JIC, their industrial variant. Although the two are interchangeable in theory, this is not recommended. Their differences are in thread class and shape and metals used.

An AN fitting is different from an AN bolt. A fitting refers to the OD the tube while in bolts it refers to the diameter of the bolt.
