AN fitting question
i am changing the rear braided line on my car over to 3/8" aluminum line and i need to buy some fittings for it. my original hard line already has a -6 AN fitting on it from when i originaly did this 5 years ago BUT its been a while and i cant for the life of me remember what i will need to use on my hard line that i have left over from then. what does the -6 and -8 and all those other numbers mean? i know i need a sleeve and nut fitting for my hard lines but it doesnt say what size tubing it is for.

They are also referred to as JIC fittings. They all have a 37* flare connection and are interchangeable with AN fittings. I have aluminum AN fittings and stainless steel JIC fittings in my engine bay. There are alot of companies that make stainless JIC adapters that may not be made in AN aluminum form for your projects.
