Flexible graphite compound gasket

    Flexible graphite compound gasket is die-cut from pure graphite plate or reinforced graphite compound plate. With its excellent resistance to corrosion and high & low temperature, fine elastic resilience and strong strength, it is a sealing element used for pipes, valves, pumps, pressure vessels, heat exchangers, condensers, etc. It can also be cut into some complex shapes, like water level gasket with bolt hole flange.
    Compound high-strength graphite gasket with covered edge has been improved with metal foil covered on both inner and outer rings. It maintains the traditional normal thickness options: 1.5mm, 2.0mm, 3.0mm and 4.5mm.
