What is the maximum length allowed for a connector or flex line?

The maximum length allowed for a connector or flex line is typically 18 inches. This length is specified in order to ensure safety and efficiency in gas piping systems. Connectors and flex lines are designed to provide flexibility and to facilitate installation in tight spaces. However, they must also maintain the integrity of the gas system and minimize risks such as leaks or pressure drops.

Using a connector or flex line longer than the allowable length could introduce potential hazards, including increased stress on the line, reduced pressure at the appliance, or higher susceptibility to damage. Therefore, adhering to this maximum length not only aligns with safety regulations but also guarantees that the appliances function properly and efficiently.

Understanding this limitation is essential for anyone in the gas fitting profession, as it ensures compliance with industry standards and protects both the installer and the end-user from potential accidents or failures.
