include a deformable portion interconnected to a vapour barrier portion by way of a mechanical or adhesive interlocking connection. This deformable portion can be made from an elastomeric material. The vapour barrier portion can be formed from a wide variety of materials that inhibit permeation of the organic vapour. Examples of the materials include ductile metals, plastic polymers and fluoroplastic polymers. The gaskets and seals can be used between the connections of the components in an automotive or consumer product fuel system. The patent also indicates that they are not restricted to this specific application, and can be used elsewhere, in similar areas.
