Reinforced graphite ring is moulded of flexible graphite tape and metallic wire such as stainless steel. Nickel etc.,according to different working conditions, metal wires are put into the flexible graphite gaskets moulding process to import its mechanical strength, so it has high mechanical strength and be suitable for valve with high temperature and high pressure.

Graphite Head Gasket can be used as sealing elements of pipe, valve, pump, pressure vessel, heat exchanger and condenser, etc.

Other complex gasket 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.
