HLG850 Graphite gasket

The 850 series is punched out of pure graphite board or graphite composite reinforced board. Excellent corrosion resistance, high and low temperature resistance; good compression resilience, good strength. It is a sealing element for pipes, valves, pumps, pressure vessels, heat exchangers, condensers, etc. It can also be cut into gaskets with complex shapes, such as gaskets for water level gauges and gaskets with bolt holes. <br> The 850E series is an improvement of the 850 series. The inner and outer rings are covered with metal foil. Maintain the original excellent performance, and can effectively prevent the penetration of the medium. <br> Common thickness 1.5mm, 2.0mm, 3.0mm, 4.5mm.
