Cylinder head cover gaskets withstand high and low temperatures to provide a reliable seal with minimal tightening. Dana only uses high-quality rubbers to satisfy the tough demands.

Cylinder head cover gaskets are increasingly produced with profiles and not flat; that is, the gasket surface is provided with beads or lips. Now, instead of the entire gasket surface, only the profile needs to be pressed, that is, the sealing bead or sealing lip, and just a slight amount of bolting force produces sufficient deformation and adaptation.
