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

Oddly enough, some years ago I had very good experience with PTFE tape for
that very purpose. We use platinum resistance thermometers to measure seawater
coolant temperatures in power station performance tests. The zinc screw on
connectors on the cables bind to the stainless top of the PRT when splashed
with salt water. I discovered that a turn of PTFE would give enough insulation
and lubrication to make the locking rings easy to remove as opposed to locking
up enough to need to be cut off after a month or two.
