There are two fairly common pneumatic quick-connect couplings (as well as a
number of others): Industrial and Automotive. Besides ensuring compatibility
between male and female couplings, are there any advantages to favor one
style over the other. For example, does one type typically flow more air
than the other?

Michael--I can't speak to flow, as I use all sizes, but the best way to
go from an interchangability point of view is to get one of those
universal female connectors--that way you can use all sizes and not
have to mess around with adaptors.
