Technically, the cylinder-head gasket is the most demanding gasket in an engine, sealing the combustion chambers and coolant and lubricant channels. The cylinder-head gasket has a significant influence on the distribution of clamping force in the overall engine system and on cylinder distortion.

- Stopper layer can be designed with topography to optimize load balance
- Improved reliability and durability
- Reduced oil consumption
- Improved engine performance
- Reduced bore distortion
Dana's MLS Stopper Technologies exhibit both plastic and elastic characteristics, making them ideal for sealing applications such as cylinder-head gaskets. This innovation utilizes topography, which creates a highly uniform seal. In areas where significant force is applied around the bolts, the waves compress more than in areas subjected to less force. Highly uniform loading reduces oil consumption, bore distortion, and overhead cam distortion. The Wave-Stopper layer forms concentric sealing rings, which provide additional micro-sealing at the combustion chamber.
Ideal for micro sealing, Victor Reinz® elastomer coatings use only high-quality fluoropolymers. Through controlled sealing pressure, these coatings fill and adapt to engine block and cylinder-head surface roughnesses, scratches, and porosities. Available coatings include full surface and partial coating.
