Description

Baxi Main Potterton Combustion Chamber Gasket Seal 5114755

The Baxi combustion chamber gasket seal 5114755 creates a tight seal within the boiler’s combustion chamber, so it can maintain safe and efficient operation. Over time, worn or damaged seals can allow heat or gases to escape, which may affect performance and safety. Therefore, replacing it with a brand new gasket helps restore a secure seal, improve efficiency, and support reliable boiler operation.
