Abstract

A composite seal of the type formed of a plurality of layers which provide a suitable fluid or gas seal between two rigid parts. The seal includes a layer of plastic material sandwiched between layers of elastomeric material, wherein the plastic and elastomeric materials are of a type not subject to cross-linkage bonding between the respective materials. The multi-layer seal is formed through use of an adhesive to bond the dissimilar layers to form a permanent multi-layer member.
