Hello,
Steam fittings are a bit of "overkill" for natural gas, Black Iron Pipe, brass, red brass are intened to be used for Natural Gas. Galvinzed iron should not be used, also use a thread sealant the is rated for natural gas do not use comon teflon tape.

What product do I need?

Need to find a way to connect something. I bought a replacement control unit for my gas water heater. The outlet is 1/2" RH thread (female), but the fitting that needs to thread in there is 1/2" LH thread (male). I went to my local Lowe's, but they had nothing. Can you please help?

Answer: 
Instead of cutting into the pipe you could use a single-strap saddle clamp with a NPT outlet. As an example Grainger item number 3ETY8 which will have a 3/4 female npt outlet.

Answer: 
Yes we do. If your supply stop has 3/8” compression connections, you may like item 11K758, which is 16” long. If your supply stop has ½” compression connections, you may like item 11K756, which is 20” long. If you need a different length, please feel free to look at the offerings on page 4172, in the current catalog, number 404.
