There are two fairly common pneumatic quick-connect couplings (as well as a

than the other?

Buy the kind that the guy you borrow his air tools uses!

Seriously, if you're talking automotive vs. industrial, I don't think there's
any difference in flow resistance, both are pretty lousy. For full flow you need
Chicago style couplers, but I don't think they make those for little air hose
like 3/8".
