What type of fitting is recommended for gas. Flare or compression? Is this specified in any building codes?

To conform with the LP gas code you need to use a flair type fitting. Compression fittings are not code for gas.
Good luck, Tom

Thanks. Does this same code go for natural gas as well?

Yep!

Are you running copper for natural gas?

Yes. We use copper for natural gas and tin lined copper for propane.

Flare fittings all the way. Good luck, Tom

Thanks. So, flare fittings are highly recommended. But is that per safety/building codes or just the right way to do it?

Have you came up with another way, besides threaded black iron pipe, to make the connections?

Both! Why are you focusing on flared fiottings? Are you seeking another way to connect the copper? Why?? Tom

We make gas lights and are working with a brass fiitting manufacturer in China. He stated to us that all of his customers that were needing connectors for gas (mainly commercial restaurant stoves/ovens) were using compression. This went against everything that we have been told so I just wanted some second opinions.

We thank you for clarifying that up.
In the States flared fittings are code. Good luck, Tom

Hello Speedball 1, I was wondering, do you know (code wise) consequences of using the compression tube fittings for Propane and Natural Gas. Are there consequences mentioned somewhere (please refer to the codes if you can) and any process to correct this mistake happened in past or just replace it? Thanks in advance.

The consequences are the brass ring cracks and you have a gas leak. IAMPO states flare fittings for gas.
