What does AN 8 mean and why is it so popular?

The AN standard comes from Army-Navy, originally developed by the U.S. military to ensure leak-proof connections in extreme conditions. Its reliability made it a staple in aviation and later in motorsport. The number 8 corresponds to 1/2”, making it ideal for higher flow lines in fuel, oil return, or coolant systems on performance vehicles.
