This is a robust and thick base gasket that is installed between the carburetor's base flange and the engine's intake manifold. The gasket is primarily designed to provide an absolute and perfect seal, thereby eliminating the risk of vacuum leaks that would otherwise ruin your engine's idle and negatively affect throttle response.

Thanks to its extra thickness, the gasket also acts as a highly effective thermal insulator. It helps prevent engine heat from soaking up through the manifold and heating the carburetor body. This significantly reduces the risk of vapor lock and fuel boiling within the float bowl, a common issue that frequently occurs during hot summer days or in heavy stop-and-go traffic with classic vehicles.

Compatible with the following carburetor models (among others):

• Weber 44 IDF
• Dellorto 45 DRLA
