What is the proper way to use gas line Teflon tape to ensure a secure and leak-free connection in a gas line installation?

To use gas line Teflon tape properly for a secure and leak-free connection in a gas line installation, wrap the tape around the male threads of the gas line fitting in a clockwise direction. Make sure to wrap the tape tightly and evenly, covering the threads completely. Avoid over-tightening the connection to prevent damage to the threads. Finally, test the connection for leaks using a soapy water solution.
