The only place to NOT use teflon tape is with Natural Gas because the
gas will react with it. (maybe propane gas too).
They make some special yellow tape suitable for Nat. gas.

The only difference (other than the color) between white and yellow
teflon tape is the yellow is thicker. White won't react w/ n-gas or the
bottled gases any more than it will, just the extra thickness aids in
getting gas-type seal w/ fewer wraps...
