If you mean NPT/Pipe threads, use Teflon tape lubed with Krytox. There are
less expensive LOx lubes I just can't remember off the top of my head as my
memory has been failing me but they'll come to mind eventually. McMaster
Carr has the Krytox, you don't need very much though. Welding shops also
sell GOx lube as well.
