Hanging out in the air will fool a temp sensor but not a pressure sensor. While air is compressible and coolant is not; still the air (or steam) is at the same pressure as the liquid since they are both enclosed by the same container.

No reason to mess up a perfectly good metric thread just to blow it up with a NPT. I hate NPT on a precision piece of machinery. An abomination against nature.
