What is the purpose of a conduit expansion joint?

A conduit expansion joint serves the essential purpose of accommodating changes in temperature within a conduit system. As temperatures fluctuate, materials can expand or contract, which can lead to stress and potential damage if not properly managed. The expansion joint is specifically designed to absorb these changes, allowing for thermal expansion and contraction without compromising the integrity of the conduit.

This flexibility is critical in maintaining the longevity and functionality of the electrical or other types of conduits, especially in environments where temperature variations are significant. By allowing for movement, the expansion joint helps prevent issues such as cracking or warping of the conduit material, ensuring that the system remains secure and operational.
