Hi

Given that you can keep feeding gas to the pot ( = minor leaks in the back yard
aren’t that big a deal …), grab a tube of epoxy and attack the pressurized side of
whatever connector happens to be handy. Probably do several layers. Run 
carefully spaced bare wires through the epoxy. 

My choice for a connector would be something circular. I’d go that way  just to 
make the mounting hole easy to drill and later maybe plug with a bolt. A 4 pin “mic  
connector” comes to mind ( and there’s one sitting loose right over there ….). 
Power, ground, signal out, signal in maybe. 

Epoxy may be overkill in this case. RTV might do the trick. It certainly would be
easier to strip off afterwords. A lot depends on just how “valuable” the pressure
pot happens to be …...

Hermetic RF connectors are available (not cheap new, but perhaps surplus), but I've only used them for 15 psi differential (e.g. atmosphere outside to vacuum inside). I've also used non-resistor spark plugs as HV hermetic feed throughs (there's some specific Champion number that has a particularly long reach).  Something like a D-sub with a dozen or so pins might be convenient, especially if it's round (since round holes are easier to drill)
