Expanded graphite cut gasket are punched or cut from pure expanded graphite sheet and reinforced expanded graphite sheet. Depand on its excellent corrosion resistance, high and low temperature resistance, good compression resilient and high intensity. All kinds of circular, complicated geometric gasket are widely used in pipe, valve, pump, pressure vessel, thermal exchanger, condenser, engine, air compressor, exhaust tube, refrigerating machine, etc.
