One more note, though. If you use an excess of Teflon tape on the threads
of a switch, such as the oil pressure switch used on the corvair, It is
possible to isolate the body of the switch from a good ground, thus defeating
the purpose of the switch. The warning light might not come on at all -
easily checked at engine start-up - but not the suggested situation. Just go
easy on the tape, or use a switch with an external ground path. And the tape
is only for use on tapered threads, as mentioned.

Yes, it works fine on NPT connections. It was designed to be used with
NPT connections. These would include oil pressure threads.
The warning is for standard flare and inverted flare fittings as found
on fuel and brake lines. Teflon (PTFE) tape is NOT designed for these
connections.
