    Should you use ptfe tape on a regulator or do yo just screw and go?

    Thanks

    Screw and go, they’re a taper fitting so don’t need any additional sealant.

    If you get to a point where you think it needs sealant, it’s time for a new reg.

    Never use ptfe on a taper fitting. If it fails to seal it needs replacing

  5. The threads aren’t meant to give you a gas tight seal, that is achieved at the seating area. Oh and the threads are parallel not tapered

    That is what I was thinking - or at least that is how the three regulators I have are designed.

    To clarify, I was on about the nipple bit, not the threads. Sorry for the confusion, will be clearer next time.

    ive wrapped a bit of ptfe on an argon mix reg after I dropped it and damaged the seal, allthough i wouldn't recommend it

    Ive put gas seal paste on my regs when I’ve needed to. Not on the threads though, just the mating surface.
