Maybe you haven’t realized a few things about AN hose fittings. “AN” stands for “Army Navy”, in reference to their original application with military equipment. AN sizes are very simple. You simply make a fraction out of the AN size. Place the AN size over 16.
For example: A “3 AN ” size fitting fits a 3/16″ hose size. A “10 AN” hose fitting fits a 10/16″ hose size, better known as 5/8″.
