Sorry to add a bit more fuel to this but am in midst of ebay argument with a German who bid on one of my lathes a 3/4 ton Colchester and he expects me to palletise and get it on the roadside for this carrier. This was advertised as collection only with assistance but this arrogant chap assumes an old uk plumber can lift this out of his workshop on a sloping site onto a pallet so he can pay by paypal then reverse the payment......scum.....rant off..............
Anyhow back to ptfe and paste.........I use a little paste but mainly to lubricate the threads so on nipping up your are experiencing resistance to the compression of the olive rather than the thread friction.

legend about the PTFE part
Tell that to boiler part suppliers: stupidly expensive parts often arrive with none of the required seals and gaskets:sad:£30 should have just about covered materials then looking at that. If compression fittings needed ptfe they would all be supplied with a roll when you buy one.
Cut pipe.
Slide on Nut
Slide on Olive
1 wrap of PTFE near the end of the pipe.
Slide olive on to it and 1 wrap PTFE over olive.
Now the Olive won't slip off, especially if in the vertical.
A touch of Blue on fitting threads over 28mm just to ease the effort required
No PTFE or paste on compression joints at all and I don't get any leaks - if one weeps I pinch it up and job is done! . . . .
Neve ever had one.Surely you will have leaks if you do every compression joint dry?
we spent years and years understanding the trade
If there's a 2mbar drop on a U6 with existing app...
Neve ever had one.
Never one leak? Not even microscopic leaks that appear as corrosion, weeks, months or years later?
Do you ever use standard compression fittings, or ballofix valves for example? You will have leaks without paste. There is no magic touch a plumber can do that will make tightening a nut a special leak proof job.
Still waiting for my first leak, it'll come one day I know that, but so far I've had none. For some reason though, I bought a tub of JetBlue today. Subliminal thought in my head from reading this thread I suppose?Never one leak? Not even microscopic leaks that appear as corrosion, weeks, months or years later?
