Serrated Metal Gasket

Serrated metal gasket suitable for high temperature & high pressure .It can use graphite on the surface Serrated metal gaskets is used for high-temperature and high-pressure general flange for piping, pressure vessel, heat exchanger, valve bonnet, etc. Serrated metal gasket has smaller contact surface compared with flat metal gasket, which has excellent sealing performance by small connecting force. If there is small hardness difference between flange and gasket, flange's contact surface can be damaged Because of the fact, flange damage can be prevented and sealing performance can be increased by applying layer such as soft graphite, PTFE, non-asb, silver, etc. for serrated surface after processing.
