Abstract
This invention relates to a metal-cored asbestos-rubber gasket wherein openings are formed in the gasket with the openings being defined by eyelets. The eyelets have flanges which engage the facing layers of the gasket and normal cracking of the eyelets incipient to incorporation thereof in the gasket is prevented by incorporating in the facing layer material microspheres in a sufficient amount to permit crushing thereof by the eyelet flanges under pressure.
