This backplate gaskets set includes multiple gaskets designed for sealing the backplate of your heating equipment. These gaskets prevent leaks of gas, water, or combustion byproducts, which is crucial for safe and efficient operation. Over time, gaskets can harden or crack, compromising the seal. Replacing them with this set helps restore proper sealing, reduce emissions, and maintain system performance. It is a practical kit for routine maintenance or repair jobs.
