Reinforced graphite gasket is an improved semi-metal gasket reinforced by a metallic mesh, foil or tanged metal. It is laminated from compressed layers of purified natural graphite flake and mechanically bonded with the stainless steel tangs to ensures the material retains dimensional stability in high temperatures.
Reinforced graphite gasket has many excellent sealing properties, such as heat stability, self-lubrication, corrosion resistance and without being brittle and aging. In addition, under extreme conditions, reinforced graphite gasket can be used stably for long time without maintenance. So it is suitable for pipe, valve, pump, pressure container, heat exchanger and condensate.
Reinforced graphite gasket can be made into special shapes.
