Thread sealer.

A bit late to chime in, but normally for this job i use epoxy. My vacuum station is all sealed with epoxy, so is my compressor and mist system. If i am in doubt that will have to unscrew it later, i use the 2euro epoxy from a chinese shop. Which works well. if propane or oil is involved, i use expensive epoxy.

As a friend said once- " all you need is one hand distance aways from you, just look around, you have it"
