I've been digging around the forum (and others) gauging the quality and opinions/reviews on various regulators and setups etc. I'm not a first time user of pressurised BTW. I sold my last one about 18 months ago, however am sourcing a new setup at the moment.
Off the topic of parts really but I notice that loads of people use PTFE tape on their regulator threads. Can someone explain why?
When I was working as a welders mate a few years ago, the welders would go mad at anyone who used it on the regulator. I would go as far to say they were in for a yellow card (disciplinary) for doing so!!!
I was told that only gas grade PTFE can be used (not normal stuff) and definitely not on the regulator. Its only used to join pipes (like compression fittings.)
The reason I noticed the use of PTFE is because it is appearing in many pictures where a leak is occuring in their system!!!!
Now I am by no meas knowledgable on this subject after all I was just the labourer however you remember these kind of things especially as I had a setup at home. Maybe its old school thinking.
I found this thread which seems to concur with them but we all know we can find info to agree or disagree on any subject!!!

Any opinions from those who are knowledgable?
p.s. I never used PTFE on mine and had zero problems. Just screwed the reg to the cylinder. Also just screwed the needle valve straight into the reg. 500g bottles lasted for a couple to 3 months with no leaks.
