NPT to AN fittings are kind of funny in that the one size down NPT fitting will give an untapered diameter through to the AN fitting. For instance, a fitting with a straight bore all the way through: 1/8" NPT to -4 AN, 3/8" NPT to -8 AN, 1/2" NPT to -10 AN etc.
It has to do with pipe being the approximate ID measurement, and tubing being the exact tube OD(with the ID being OD-2*wall thickness).
