Which of the following is NOT correct regarding the usage of shipment fittings in installations?

The choice indicating that shipment fittings are required by code is not accurate. Shipment fittings are typically intended for temporary use and may not meet the requirements for permanent installations. In various jurisdictions, specific codes outline the standards and practices for gas installations, and while shipment fittings can indeed provide convenience, they may not always comply with these regulations.

It is essential for gas technicians to use fittings that adhere to local codes and standards to ensure safety and reliability in gas installations. Codes generally specify the types of fittings that must be used for particular installations to prevent issues like leaks or failures over time. Therefore, saying that shipment fittings are required by code does not align with the regulatory framework in most cases.
