Seal a steel gas pipe by first ensuring the gas supply is turned off. Use thread sealant tape (Teflon tape) specifically rated for gas lines, wrapping it tightly around the male threads of the pipe. Apply a pipe joint compound for added security. Connect the pipe, tightening it with a wrench. Check for leaks by applying a soapy water solution—bubbles indicate a leak that needs further tightening. Always follow safety guidelines and consider consulting a professional.
