Is that correct and if so, why?
It is best not to use Teflon tape as it can shred and clog parts of
your system - a problem you will not encounter with Pipe Sealer with
Teflon. Another problem I recall was in a plant here in Houston years
ago when Teflon tape was used in fittings on a fuel loading hose.
Apparently, the tape was thick enough to act as an insulator and
allowed static electricity to build rather than discharge to ground.
When the operator touched the nozzle to the lip of the filler a spark
ignited the gasoline.
AHAA!! - So that's why 'they' made me get that expensive thread sealer for
the fuel delivery system at the golf course shop. Live and learn - ain't
life wonderful.
