Abstract
An embodiment provides a MLS gasket that includes a metal layer having an external periphery, an upper surface generally defining a first plane, and a lower surface generally defining a second plane. The first and second planes define a layer thickness therebetween. At least one cylinder aperture is formed in the metal layer. The metal layer includes a stopper portion formed adjacent at least a portion of the external periphery. The stopper portion is formed such that at least a portion of the stopper portion extends above the first plane. At least a portion of the stopper portion extends below the second plane. An average thickness of the stopper portion is less than the layer thickness. The gasket also includes a first sealing layer adjacent the metal layer. The first sealing layer includes a first bead portion. Compression of the first bead portion is selectively limited by the stopper portion.
