What size -AN size do I have?

I'm replacing a hydraulic TOB and I'm not certain as to what -AN size I'm currently running, I'm not all that familiar with them. Most all aftermarket use a -3AN but I think that I'm currently using -4AN. I took my calipers with an indicator and read .162 on the ID of the male fitting. Can anyone tell me off of that info wether it's a -3 or -4?

Thanks for any and all help!

 

That would be -3......the dash ( - ) = 16ths of an inch.
-4 would be 4/16 or 1/4 inch (.250)

Most that I have seen use -3AN hose so -3 AN fittings should be what you need.

 

Thanks, that was certainly simple enough! Knowing that each increment is over 1/16" takes the guess work right out of it!
