You can also Google it.

I would use brass, though the last 3/8" brass elbow I bought could have been solid gold, for the price.

You should use brass or black, not galvanized pipes for gas service per code in many areas.

Almost every gas oven and clothes dryer uses brass to black iron fittings.

We never use galvanized fittings for propane or NG up here. Since you are connecting to brass it's best to get a brass fitting as a black iron one would cause galvanic corrosion because of the dissimilar metals in contact with each other.

If the hose connection is a flare, tape is not used on flare connections.
Yellow tape is thicker and resistant to petroleum products.
Get a brass elbow which will match the other metals in that assembly.

Da?n spell check!

Galvanizing might flake off also.

This was my first thought too!

When I use a threaded gas fitting I use "gas" line tape it's yellow instead of white. That way when I go back to fix or look at something I know what I worked on and what I didn't.
