Fittings..... Want to buy fittings for plumbing ,fuel and misc. other lines. Is there some kind of chart that explains what the different "AN" minus whatever means??? Like what size those numbers are equivalent to? For example : "AN -1 or -10". ??

AN = Army Navy specification
it is a fraction of 16 for the OD of a metal tube
Example:
-8 AN = 8/16" = 1/2" OD of the metal tube but equals 0.440 ID

This should move to a different forum though...

Oh, and I think that this thread is off topic for the section it is in, when a simple google search can find the answer to your question there is no need to put it in advanced tech.
