    I'm thinking about redoing some of the plumbing on engine/tranny/tranny cooler. Particularly, I want to get rid of some hose clamps and use compression style fittings. Could anyone point out to me where I could look up AN fittings and braided hose sizes as compared to hose ID/OD and pipe thread sizes, and also thread style? I know about the 37° vs. 42° flares; all I'm looking for would be a table shoing what e.g. a 6-AN is in real measurements. TIA, michael

    good question!
    check out my post in the garage forum-nearly the same topic.
    I have been doing my homework and found that the AN fittings are a # over 16. Example, 8AN size is really 8/16 (or 1/2).
    Dont think that all sizes are an exact match.
    Hopefull someone else knows the complete story.
    Good luck
