A rubber metal gasket excels at great compression ratio at low surface pressure. A fully rubber-jacketed support ring guarantees ideal sealing attributes even with low bolt forces.
The rubber metal gasket withstands high temperatures and mechanical stress e.g. vibration and pressure shocks.
Often, the complex geometry of the gasket profile is made with a curvature, which also enables excellent seal for the unsuitable parts of the sealing.
Rubber metal gaskets are specially used in applications where it is difficult to reach the efficient surface stress with normal static gaskets. For example, in oil pan applications.
