Since we're giving Iggy thread advice, let me add this: I sometimes
have a taped joint leak. I never have a leak on a joint where I've
used "paste" sealant. With PTFE or Teflon.


Teflon IS PTFE.

I've seen plenty of paste sealant joints leak whether done by myself or
professional gas fitters on various pressure systems including low
37mBar systems. They should always be checked.
