If you don't plan to use it for the heater, then you might be able to find an appropriate sized freeze plug. They also make the removable rubber freeze plugs, that you expand by tightening a bolt. That might not give you the appropriate warm fuzzy feeling in a plane though. If it happens to be close to the right size for an NPT tap, that would work too.
