New gas water heater, gas adaptor
Thank you for taking the time to read this. I just got a new gas water heater. It has a fourth inch copper gas line running from my main line. My question is do I have to use a flare tip adaptor or can I use an adaptor sans flare tip and maybe use dope to prevent leaks?

No sir. It's natural gas.

Although I've seen it used many times, I don't believe soft copper tubing is compliant with the fuel gas codes for a natural gas connection. Lawrosa could shed some light on this.

I have seen it used , to . One occasion ( an Uncle ) the chemicals in the gas caused corrosion in the thinnest part of the line . Which was the flare . This resulted in a leak . :-(
I told him and Dad I did not think they should use it . They asked ifould fix it . I said yes , dug out my tubing cutter & flare tool . Cut the old flare off ( there was sufficent slack to re-do this ) and re-flared the end of the copper .
I do not know if copper is approved for propane ?

I remember seeing a number of natural gas fired unit heaters in a warehouse connected with soft copper tubing that stopped working because the gas valves were all plugged. The copper tubing had a silvery looking substance in it that looked like droplets although it was dry. All required new gas valves and the appropriate flex connector and all worked fine thereafter. There is a type of hard copper pipe approved for natural gas with silver soldered fittings, but I cannot tell you the type. I prefer black iron piping.

Me too , with the black iron pipe . I think the new flex gas " hoses " are made of stainless steel ? ( I know they are not hoses , but I could not think of a correct term to call them ? )
