does the green a/c oil ring....
... look bigger or smaller when new -- compared to the old one you are replacing? Like radiator hoses, the new ones are usually smaller looking due to it not being stretched yet . But does the same principle apply to A/C green O-rings? I was changing my exp valve and the new ring seems to be smaller in thickness but the same diameter or should I say prettty darn close to the old one.Not to mention a little darker in color as well.
I just want to put the wrong one, esp. if I accidentally put the wrong one in the evaporator area..Too big of a job make such a small mistake.
