What are kammprofile gaskets?

Kammprofile Gaskets are composite gaskets, which utilizes a serrated metal core with a soft material. The metal core is machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads. The result is a gasket which combines the benefits of soft cut materials with the advantages or sealing integrity associated with metallic gaskets.

Expanded graphite is the most common facing material used for Kammprofile Gaskets. However, other materials can be used, such as PTFE for chemically aggressive duties or mica for high temperature duties, etc.

Types of Kammprofile Gaskets

Basic style kammprofile gaskets

* This type kammprofile gasket for tongue and groove flanges
* Gasket without inner and outer rings
* Concentrically grooved profile on both sizes and covered with soft material layers

Kammprofile gasket with integral outer ring

* Kammprofile gasket with machined centering ring
* The metallic core is made with a concentrically grooved profile on both sides and a machined centering ring
* Gasket with soft sealing layer both sealing surface

Kammprofile gasket with loose outer ring

* The metallic core is made with concentrically grooved profiling on both sides
* A notch is turned on the outer circumference of the core in which a loose centering ring
* With soft sealing layer in both sides
