Can you use white Teflon tape for propane?

It's only necessary on pipe thread fittings.As you tighten the fitting, the pipe threads bind together and form a seal.I would not use tape on the flare fitting, even if it did not cause any problems.

Is white Teflon tape gasoline resistant?PTFE tape is both oil and petrol resistant, which is why it's used to seal and lubricate joints around fuel lines in automotive applications.

White and yellow Teflon is supposed to be used for water and gas pipe thread.

Wrap Teflon tape around the threads of your tank to begin the installation of the propane tank fittings.Even if the connection is too large, this will allow you to get a good seal on your fitting.The compression fitting needs to be pushed firmly onto the tank.
