Serrated Metal Gasket

Serrated Metal Gasket
	Serrated Metal Gasket is normally called Kammprofile Gasket and widely used on High pressure & high temperature plumbing flanges and is ideal for the pressure vessels, heat exchangers and Valve bonnet. Serrated Metal Gasket has smaller contact area and has excellent sealing effect with lower torque than Flat Metal gasket, however, it may occur flange damages it the hardness of Flange & Gasket is same or the difference of the hardness between Flange & Gasket is very little. In this reason, Soft Graphite, PTFE, or Nonasbestos layer can be attached on the surface of serrated matal gasket and it prevent Flange damages & enlarges sealing efficiency.
