Abstract
A multilayer metal gasket () having first () and second () functional layers. Each layer () includes an opening (). Sealing beads () are formed in each layer () and, preferably, arranged to contact each other in crest-to-crest orientation to perfect a seal therebetween. A stopper feature () is provided to restrict compression of the sealing beads () in use. The stopper feature () is arranged in a generally circular pattern and is composed of a plurality of discrete nesting embossments () which are closely spaced to one another but do not touch. Each discrete nesting embossment () is substantially identical in shape to the next adjacent discrete nesting embossment () but oriented approximately 180 degrees therefrom. The embossments () may be formed entirely on one of the functional layers () or on both functional layers.
