Union fitting for gas

Could you tell me if I put TFE paste on the outer most thread. The gas line is 3/4", I mean the large outer most thread which allows you to tighten both pipes together. My thought is no because it is a flare or compression fitting.

Not needed but you can if you like.


Fix it right the first time, so you won't have to fix it a 2nd time.

It is not necessary but could aid in loosening it in the future if needed. I got in the habit of using Never-seez on steel pipe unions for just this reason.
If you have never made a mistake, you haven't done much.
