I use a small amount of teflon tape.
Spent time as a plumber, taught by old school tradies.
If teflon tape is applied to the threads properly, there's no way it can migrate INTO the hole.
The action of screwing the fitting in will push / compress the tape up the fitting thread, NOT into the hole.
Same with pastes and thread lockers, as you screw a fitting in, a lot of the paste stays put, and the thread has less and less paste on it the further you screw it in
Lots of people, plumbers included don't do a good job with teflon because they don't understand it.
I never liked thread sealing pastes. Lazy people really on them too much IMO (that's not to say they don't have a place). I've seen leaks that don't make sense where paste sealed joints have failed. Seen it as a plumber (workmates used it), and as a builder.
I've talked to owners of plumbing companies who don't allow their guys to use it, and get pissed off when they do.
