gasketing has developed from the early days of copper, leather and basic cork
to non-asbestos, silicones and a variety of metals.
engine demands high pressure sealing and must cope with differential rates of
expansion and contraction between flanges. Engines are constructed from
alloys with less contact area for the gasket to do its job, but with greater
The development is toward embossed or laminated metal with selective coating
and also flat metal covered with gasket materials, which are in turn,
enhanced with silicones. The result is a gasket which conforms to surface
irregularities which can accept surface movement, can seal under arduous
conditions and can be easily removed. More use is being made of new materials
and enhancing the gasket with silicon coating and silicon beads adds to
improved performance of the gasket.
AND VALVE COVER GASKETS
Oil pan and valve covers in pressed metal format use a variety of rubber
mouldings and CorkRubber provides a good seal. On
cast aluminium types, non-asbestos materials are more applicable. (Refer to
our product range and specification).
Metal gasket composites (or metal clad jointing) allows for differential
expansion rates between the manifold and engine whilst sealing exhaust gas at
