This rubber shutter gasket provides a tight seal around the air shutter or damper mechanism in your boiler or burner. As part of your heating equipment components, it prevents unwanted air ingress or leakage, helping to maintain correct combustion settings. Over time, rubber gaskets can harden or crack, leading to efficiency loss. Replacing with this durable gasket is a straightforward way to improve burner performance and ensure safe operation. It is a common spare part for routine maintenance of gas burner systems.
