I should have clarified... I sometimes do work in, and occasionally borrow tools from, a couple of other shops. All three locations have different systems. A real inconvenience to have to swap air plugs everytime you want to use a tool, which is what led me to ask about the universal types.
Changing my system to match another would be easy enough, but I can't match both, so I guess I'll need to make some adaptor fittings.
Thanks for the replies.
