What type of fittings are required for mobile home gas installations?

Flexible fittings are required for mobile home gas installations primarily due to the unique characteristics and requirements associated with mobile homes. These fittings are designed to accommodate the movement and shifting that can occur in mobile structures, which can be caused by factors such as wind, transportation, or even ground settling.

Using flexible fittings helps prevent leaks that could arise from rigid connections, which may crack or fail when subjected to movement. Additionally, flexible fittings often allow for easier installation and adjustments in tight spaces, which is particularly important in the confined areas typical within mobile homes.

This choice aligns well with safety standards and best practices in gas line installations, ensuring that any potential hazards related to gas leaks are minimized by using materials specifically designed to handle the dynamics of mobile home environments.
