I have some -AN fittings, but i'm not sure what size it is. I measured the Major Diameter of the threads with a set of calipers and it's 0.75 inch.

I searched google, but i can't find any good schematics.

Is this -AN 8 or -AN 10?

Here is a picture of a fitting, and what I measured. It's not the actual one I have.

Hey ben, thanks for the link, but It doesn't give any dimensions of the threads. I have that fitting on an oil cooler, and i''m trying to figure out what hose end to buy.

12/16 = .75

therefore -12AN

I may look like an idiot here but that sounds like an -8 to me, all my stuff is 8 or 6 and that seems about the size of an 8. what is it on?? or for??? I also believe you measure AN fittings to the inside diameter, not the thread size.

AN is ID not OD. Measure the ID of the fitting. Then if it measured .75ID it would be 12/16" = .75 = -12AN.

i always thought that the an number stands for hose diameter. The fittings always looks bigger in diameter.

i just found this site here.

according to the chart

-AN 8 has a thread size of 3/4-16 SAE
-AN 10 has a thread size of 7/8-14 SAE
-AN 12 has a thread size of 1 1/16-12 SAE

For that thread size nomenclature, is that first number the major diameter of the thread?

also JIC and AN are the same but you can get JIC in brass and steel.

Yes. Major diameter-thread pitch is the standard way of expressing straight cut threads.
