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".

The _continuing_ problem in this country, is the lack of standardisation. If
only we just had the metric system here, we wouldn't have these problems.
A memory from the motor trade: At one time, there were three different
thread types used on a BSA Bantam m/cycle swinging rear fork spindle: BSF,
UNF fine, and Cycle.

Surely adding the metric system simply adds MORE non-standardisation?
All these BSF, BSW etc predated ISO metric!
Even the metric system has its own variations as well!
