In layman's parlance, Teflon. But 'Teflon' is a registered trademark, so
PTFE is shorthand for the chemical name, which I don't recall offhand.

No, PTFE actually works as an anti-seize as well, as long as you don't
exceed 500F. Hopefully, your fuel lines don't <G>
But, it's only useful as a sealant on tapered thread fittings (same place
you could use "teflon tape"). If your fuel lines are flare or compression
fittings or something like that, then the PTFE paste won't help with
sealing. Still works good as an anti-seize, though ... I use it for that on
rubber radiator hoses.
Hmm, I probably need to add a disclaimer here to the effect that even though
I work for a division of John Deere, my opinions are not necessarily those
of John Deere.
