حشية شفة/المبادل الحراري باكسي De Dietrich 7880112

The gasket between the flange and heat exchanger in Baxi boilers creates a tight seal that prevents water and gas leaks. This gasket is subjected to high temperatures and pressure, so it must be made from heat-resistant and durable materials. Over time, gaskets can harden, crack, or compress, leading to potential leaks and reduced efficiency. Replacing this gasket during routine maintenance or after disassembly ensures a proper seal and safe operation. It is a common spare part for boiler repair and helps extend the life of your heating equipment.
