Gasket for IC engine manifold

摘要

The metal gasket comprises at least one metal plate including at least one fluid hole. A main bead extends around and adjacent to the fluid hole, and at least one auxiliary bead sitauted at an area away from a tightening device of the gasket. The axuiliary bead diverges from a part of the main bead, extends along the main bead and again merges to a part of the main bead.An area adjacent the tightener is sealed by the main bead. The area away from the tightener is sealed by the main bead and auxiliary bead to provide equal sealability around the fluid hole when the gasket is tightened
