Tappo superiore De Dietrich 7776745

The top cap is the uppermost cover of a boiler or burner housing, providing protection and completing the unit's enclosure. It helps prevent debris from entering the system and maintains proper airflow around internal components. As a spare part, the top cap is often needed after damage or during refurbishment. For anyone handling boiler maintenance and repair, this simple but essential piece ensures the heating equipment remains fully enclosed and safe to operate.
