Ionisation sensor gasket De Dietrich 7705920

The ionisation sensor gasket provides a reliable seal around the flame sensing electrode in boilers and burners. This small but important part prevents gas leaks and ensures accurate flame detection, which is crucial for safe operation. Made from heat-resistant materials, it withstands the high temperatures near the combustion chamber. When replacing an ionisation sensor, using a new gasket is recommended to maintain a tight seal and avoid false readings. This gasket is a common spare part for boiler maintenance and repair, helping to keep your heating system running safely and efficiently.
