Can plumbers puddy be used to seal gas pipe (black pipe) fittings?

Plumbers putty is not for pipe threads. But if your trying to fix a leak You
going to have to take it apart. That usually involves taking apart more than
you want unless the leak is at the end. When putting back together here what
I do on gas pipe. I use retorseal and Teflon tape I never used a special
Teflon tape for natural gas ( I have for Med Gas) First I put rectorseal on
the threads then about 5-6 clockwise turns of Teflon tape then more
rectorseal . I have put allot of gas pipe in this seems to work. If you
have to take out a major amount of pipe to get to the leak you can cut the
pipe and thread the cut end ( hand threader) and install a Right and left
hand nipple or a union ( union must be assessable) I prefer L F nipple.
Either way do your math before cutting.
