That's what I've always assumed too, but BSS seem to think otherwise -Starting from open end has my vote.
What do others think?PTFE tape is applied to the male thread in the direction it runs i.e. starting away from the open end of the pipe and working towards the open end.
BSS are right and if you look at picture on one wrap tape it shows you this, have never heard of anyone saying start at open end and work way back up thread always the other way. Or perhaps this is the gas method
Though I dont use PTFE anymore as I prefer Loctite 55.
