Just to continue Dave’s point here if you are not over familiar with thread sealing especially with something like this pressure gauge, it is the actual contact of the PTFE tape against the faces of the threads on the internal and external part that stop it from leaking.
With the correct amount of PTFE, it will be easy to get the gauge in the correct orientation.
On my synchronika I once set mine so the number nine was at the top but my wife soon made me change it 🤪🤔😶
There is a misconception that it has to go all the way to the bottom but in this case there is nothing to seal / bottom out by going all the way to the bottom.
