Intake manifold rubber

The intake rubber is a relatively simple product, but nevertheless very important for the function of the intake and carburetor. It must seal 100% to ensure optimum engine performance.

It connects the metal intake manifold to the carburetor, in carburetors with intake rubber assembly. On 4-stroke engines, the intake manifold is often just a simple intake sleeve; on 2-stroke engines, the intake manifold itself is often flexible so that the carburetor can be attached directly to it.
In some cases, the rubber flange serves as a kind of adapter to change the type of mounting and allow the use of a different type of carburetor (e.g. Peugeot Speedfight).
