Graphite gaskets are cut from pure graphite sheet or graphite sheet with metal reinforcement, features excellent corrosion-resistance, high-and-low temperature resistance, good compression resilient and high intensity it can be used as sealing elements of pipe, valve, pump, pressure vessel, heat exchanger and condenser, etc. Other complex gaskets such as water gauge gasket and flange gasket with bolt holes are available. Wrapped with metallic stripe in the inner and outer circle borderline. Keep the former excellent performances. Can be installed and disassembled conveniently without damage.
Size and construction – custom made gaskets
Gaskets are available in EN 1514-1, ANSI B 16.21, other Standard Forms, or as custom made gaskets.
