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