Would you resist using a blowtorch if you were using solder joints?

This is what PTFE is for,

********!!

very rarely can a watertight seal be achieved without it....they just
don't tighten up properly.

A compression fitting is DESIGNED to give a watertight (and gas tight
- with the correct fiiting) with only itself and the olive. PTFE
tape is not a '"must include" extra for every fitting. If done
correctly a compression fitting WILL be leak free without PTFE.

I have to agree with him Phillip PTFE was primarily a temporary fix
solution in the early days of it appearing on the market until a
satisfactory job was known to be good.

As the man said...
"If done correctly a compression fitting WILL be leak free without PTFE".
