Kammprofile Gasket (Serrated Metallic Gasket) consist of a metal core, generally stainless steel with concentric grooves on both sides. A sealing layer is usually applied on either side and depending on the service duty the material for this layer can be expanded graphite, PTFE, Asbestos free gasket sheet materials or some soft metal. It can be used without sealing layers to provide an excellent sealing but there is a risk of flange surface damage especially at high seating pressure.
 
Serrated Gaskets/Kammprofile Gasket Features
1.Suitable for a range of chemicals
2.Suitable for use in high pressure and high temperature applications
3.Can be refurbished and reused
4.Can be manufactured to suit standard flange applications and vessels.
5.Can be manufactured for use with narrow flanges
6.Better leak tightness than spiral wound gasket
