Gas piping outlets that penetrate a wall must extend through the wall by at least

Explanation:
The main idea is that any gas piping that goes through a wall needs a small, intentional amount of pipe sticking out beyond the finished wall surface. Extending the pipe at least 1 inch provides enough exposed length to attach or cap the line, to securely fit connectors, and to prevent the end from being damaged or recessed inside the wall where a fitting can’t be reached or tightened. This small extension helps ensure a proper, accessible connection and reduces the chance of leaks or damage as the wall is finished or as future work is performed. Extending more than 1 inch isn’t required by the standard practice and would just protrude more, making finishing and aesthetics harder without added safety or functionality.
