Wireless card connectors might work they're very similar, but you'd have to remove the center pin to allow for air flow, and there's no way to get two electrical connections, as the body is a single ground point, really the only thing you can replace that connector with is another one of that type, it's a very specifically purposed type of connector.
It would be larger but using two separate connectors, one for the two wire electrical and one for the air flow would be much more practical unless you can find a source for similar two electrical and one gas connectors, you're really only going to find something like that from a medical distribution supply company. Digikey might carry something like it but I have no idea what to call it. A e-mail or call to a Digikey salesperson might provide you with more information.
