It can certainly do both (isn't that one of the reasons it's called
"MultiFailure Temp Sensor")? Anyway, the MFTS installations I've seen
generally show some sign of external leakage. I would think that
teflon tape (or any sealant) might be problematic because the MFTS
depends on contact with the cooling pipe for the electrical ground.
