Here is a little info about -AN fittings.

Divide the size of your AN fitting by 16 and that gives you the fractional size.

For instance a -6an fitting is 3/8 because 2 is the common denominator of 6 and 16.

2 goes into 6 THREE times (over) 2 goes into 16 EIGHT times. Thus 3/8

-12an is 3/4 as 4 is the common denominator.

4 goes into 12 THREE times (over) 4 goes into 16 FOUR times. Thus 3/4.

Hope this helps!
