Flue sensor cap De Dietrich 59659

The flue sensor cap is a protective cover designed to shield the flue temperature or pressure sensor from debris and mechanical damage in boiler systems. It ensures accurate sensor readings, which are critical for safe and efficient combustion control. When servicing heating equipment, replacing a missing or damaged flue sensor cap can prevent false readings and potential system shutdowns. This cap is a simple yet important spare part for boiler maintenance and repair.
