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.

Years ago I added larger diameter gas pipe in our house. I asked what
sealant to use on the black iron pipe and was told to use the yellow
teflon tape. EVERY joint leaked. By the time I got to testing for
leaks the next day a bunch of the pipe had been framed in because we
were remodeling part of the house at the same time. So I had to
unscrew pipe that obstructed by all sorts of framing. GRRR. I then
called the gas people and they said "Rector Seal". No leaks with that
stuff. Kinda goopy but seals way better on crappy black iron pipe
threads.
