When gasket width has to be narrow as in cylinder heads and exhaust manifold on internal combustion engines, compressed asbestos fibre (“CAF”) sheets and compressed asbestos-free (non-asbestos) fibre sheets are reinforced with mesh wire gauge to resist the blow out. Sheet jointing of pure exfoliated graphite are reinforced with a central layer of 0.1mm thick tanged stainless steel to give them extra strength for easy of handling and fitting. In these gaskets the graphite is compressed onto the perforated metal sheet to give a secure mechanical lock without adhesive. Extra strength to such sheets is also given by bonding a central layer of stainless steel or nickel foils.
