So...interesting debate time!
There are alot of plumbers who swear blind by using PTFE tape on compression joint threads (3 turns clockwise or whatever).
There are also many people who say you SHOULD NOT do this.
Reason:-
1) The seal is created by the olive crushing into the pipe and the olive against the joint - not the threads.
2) Using PTFE can clog the threads and thereby prevent the threads doing their job which is to compress the olive against the joint.
3) If the olive leaks, the PTFE does nothing anyway and the joint will leak.
So...whats everyones opinion? Use PTFE on copper compression joints or not?
What about where to apply PTFE...threads only or on the olive as well?
