Abstract
A gasket has two outer facing layers positioned on opposite sides of a central metal shim with a perforated core disposed between each facing layer and the shim. The width of the metal shim may be varied to control the overall width of the gasket. The core is secured to the shim using a thermosetting adhesive and includes tangs which extend into a facing layer to clinch the core and facing layer together. The use of a perforated core prevents blistering of the facing layers during gasket manufacturing. The two perforated metal cores separated by an adjustable width shim provides manufacturing advantages, minimizes facing layer thickness, and adds strength.
