I've come to understand that the tape is not for sealing. It is to keep
the threads from corroding together and allow for removal. Having recently
taken a steel fitting out of an aluminum casting, still holding the aluminum
threads, it makes perfect sense.
I use hylomar or Indian Head shellac for sealing threads. No leaks yet.
