A flexible connector is primarily used in gas piping systems to provide flexibility. This flexibility is crucial because it allows for movement and adjustment in installations where thermal expansion and contraction may occur. Gas appliances and the connected piping can shift due to temperature changes or other forces, and the flexible connector absorbs these movements without causing stress or damage to the piping system.

Using rigid piping exclusively can lead to breakage or leaks, as it does not accommodate such movements. Thus, these connectors are essential in ensuring the safe and reliable operation of gas appliances by facilitating the required flexibility. Their design allows them to handle the specific demands of gas installations while maintaining a secure and leak-free connection.

This aspect of flexible connectors is vital in both residential and commercial setups, where space constraints and appliance mobility may need to be considered.
