CAZ KammprofileTM 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 sheeting 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.

CAZ 630 Corrugated Metal Gasket consists of a metal core with concentric grooves on both sides, coated with expanded graphite or PTFE layer. The thickness of metal can be thinner, e.g. 3mm, 2mm, 1mm, 0.5mm, compared with 620 Kammprofile gasket, and the corrugation pitch is 3mm, 4mm or 6mm depending on the width of the sealing face.
