People at HD and other places like that are for the most part, IDIOTS.
I'm surprised they didnt sell you a garden hose for the gas.

Natural gas is piped thru BLACK STEEL PIPE ONLY.

Umm..no.
NG can be, under some circumstances, be piped in copper, altho, as I said
before, it depends on the supplier of the fuel, and local codes...the
International Gas Code states the reasons and where it can not be used.
NG can be piped in things like PVC (underground only, the gas company does
this) and stainless steel. Stainless steel flex is fast becoming the
prefered way as its about 5X faster to run, can be ran in places iron pipe
cant, and is much lighter. 200 feet of TracPipe 3/4 with the roll only
weighs 40lbs.


Propane uses copper (or steel).

Again...not always. Propane lines can be just as above...black pipe (iron)
stainless flex, or copper. Some apps wont let you use copper for this
either.


When you connect the black pipe, DO NOT use teflon tape either. Use
pipe dope (liquid paste). (there is a special teflon tape made for
gas, but if you can find it, it's expensive.

The only real difference in that tape is that its yellow, and will still
clog prefilters and such and no real self respecting pipe fitter will use
tape on any gas fitting.

The dope is cheaper and
has been used for decades).

There's no problem with running natural gas in copper. It's run that
way often in industrial and laboratory installations.

Hey EL , Plain copper tubing it never used on any natural gas transfer
tubing lines at all unless they are lined with some type of coating like
AL.
or epoxie coating to prevent the chemical reactions to make the Sulfur
drop
out of the natural gas and only if it has any left in it when it is used.
Also you have copper oxide to deal with in the burning equipment in these
so
call lab burnering equipment your speaking about. If you check you will
find
they are lined with a coating and not regular copper tubing lines. Now I
have been told by the manufactors of propane equipment that regular
copper
can be used because propane is not suppose to react with the plain
copper.

So, plain copper tubing is never used on natural gas lines in industry or
laboratory installations unless they are have a liner coating in them.
