Yes, you can. You could also use pipe dope, according to my dad. He works for infra source installing natural gas piping.
When the local codes allow its use on the piping as some codes do restrict the use of tape
There are approved Teflon tapes for "gas" but it depends on the HJA and what type of "gas" your asking about
Use the yellow tape. Its specifically for gas. I also use a small amount of pipe dope on the female fittings. Pressure test the new work separately, or if its a small add on use a soap solution to test your work.
Many fittings, except unions, require the use of teflon tape.
Teflon
Using white Teflon tape on a natural gas pipe is not recommended because it is not suitable for use with gas fittings. Teflon tape is typically used for water piping applications. It may not provide the proper seal for natural gas, leading to potential leaks and safety hazards. It is best to use yellow Teflon tape or an approved pipe joint compound specifically designed for natural gas applications.
If you are running natural gas or propane, gas teflon tape. Otherwise, any white teflon plumbers tape is fine.

Blue Teflon tape is thicker and denser than white Teflon tape, making it more suitable for sealing larger pipe fittings. White Teflon tape is thinner and better for smaller fittings. For plumbing applications, blue Teflon tape is generally preferred due to its higher density and better sealing capabilities.

Certain restrictions regarding Teflon such as gas piping require a different type of teflon appreoved for the type of fuel going though the piping When connecting tublar waste lampwick does an amazing job not to be confused with quickwick
No, white Teflon tape should not be used on gas lines for sealing purposes as it is not rated for use with gas and may not provide a secure seal. It is recommended to use yellow Teflon tape specifically designed for gas lines.

The recommended type of tape for sealing natural gas connections is yellow gas line tape, also known as PTFE tape or Teflon tape. Teflon tape is commonly used for this purpose because it is resistant to chemicals, temperature changes, and high pressure, making it a reliable choice for sealing gas connections securely.
The recommended type of tape to use for sealing gas pipe connections, especially when working with natural gas, is gas Teflon tape. Gas Teflon tape is preferred over other types of tape for this application because it is specifically designed to withstand the high pressure and potential leaks associated with natural gas, providing a secure and reliable seal.
The recommended method for sealing threaded connections in natural gas pipelines using Teflon tape is to wrap the tape around the male threads in a clockwise direction, making sure to overlap the tape by at least half the width of the tape. This helps create a tight seal and prevent gas leaks.
Many fittings, except unions, require the use of teflon tape.
