The Baxi 242500 Heat Exchanger Rubber Seal is a genuine replacement gasket designed to provide a secure, watertight and airtight seal around the heat exchanger in compatible Baxi boilers. This seal ensures correct pressure retention, prevents leaks, and supports safe, efficient boiler operation.

Over time, rubber seals can harden, crack, or degrade due to heat and system wear, leading to water leaks, pressure drops, or combustion issues. Replacing the seal with this genuine Baxi part restores proper sealing and reliable boiler performance.
