The Baxi 247435 Viewing Window Gasket is a genuine replacement sealing component designed to ensure an airtight and secure seal around the inspection window in compatible Baxi boiler models. This precision-made gasket helps prevent combustion gases and moisture from escaping through the viewing window area, supporting safe boiler operation and maintaining correct internal pressures. Made to Baxi’s exacting quality standards, it should be installed by a qualified heating engineer during servicing, maintenance, or when replacing a worn, hardened, or damaged gasket.

Compatibility for the 247435 viewing window gasket includes Baxi Combi, Platinum, and System boiler models that utilise this specific gasket size and profile. Always verify your boiler’s exact model and part specification before fitting to ensure the correct match and reliable performance.

Using a genuine Baxi viewing window gasket helps maintain proper combustion integrity, supports efficient and safe boiler operation, and contributes to the long-term reliability and performance of your central heating and hot water system.
