Venturi gasket (5 ps) De Dietrich S54777

The venturi gasket is a critical sealing element used in gas burner assemblies to maintain the correct air-fuel mixture. It sits between the venturi and the burner body, preventing air leaks that could affect combustion efficiency. This gasket is designed to withstand the heat and chemical exposure typical in heating systems. Replacing a worn or damaged venturi gasket can restore proper burner performance, reduce emissions, and improve overall system reliability. It is a simple yet essential part for any gas-fired boiler or burner maintenance kit.
