Gasket Type METAGRAPH – ER
Seal made from reinforced graphite sheet grater: ns. METAGRAPH G reinforced with a metal eyeleted internal, external or both sp.0.10 mm. To enhance the sealing performance. The metal piping, in fact prevent the erosion of the seal preventing the infiltration of graphite foil and allowing them to retain the mechanical properties and a significant reduction of fugitive emissions.
Chemical, petrochemical, exhaust systems, thermal power stations, valves, pipes, food industries etc.. and in harsh automotive resisting high mechanical and physical properties.
