AN (Air Force/ Navy) spec hose and fittings refer to dash sizes. This is caculated by multiplying the nominal bore size by 16.
example : You want a AN fitting for 1/2" hose, Take 16 x .50 (1/2") = 8 So you would need a -8 AN
example: You want a AN fitting for 3/8" hose, Take 16 x .375 (3/8") = 6 So you would need a -6 AN
example : You want a AN fitting for 1/4" hose, Take 16 x .25 (1/4") = 4 So you would need -4 AN
Hope this helps you with AN sizing.
