I'm happy to have everyone agree that pipe compound is superior, but do note
that natural gas is a *very* low pressure system, usually by law. The
disasters I mentioned happened at 100 psi or above. The only problem with
using any kind of teflon tape in the low-pressure (post regulator) side of
your system probably is a permanently clogged needle valve. If you are
careful in applying it, as Johan said, it *is* pretty safe. 

The same goes for pipe compound. It is usually petroleum-based, and could
give a nasty surface film in your tank if used carelessly.

Maybe that would cut some surface CO2 loss? :^)

The bottom line is that use of teflon tape in high-pressure gas line
fittings should not be recommended, just like using solder on 120Vac
electrical fittings. You may get away with it for years, but you would never
get Underwriters Lab to approve it. It really isn't safe.
