KAMMPROFILE GASKET is a composite gasket which utilizes a serrated metal core with a soft facing material.
The Kammprofile is a composite gasket which utilizes a serrated metal core with a soft facing material. The metal core is machined on each contact face with concentric serrtions which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relativelylow bolt loads. The soft facing material is engineered to compress in to the serrations on the core and form a thin film across the peaks creating the ideal sealing density in the grooves of the profile. The result is a gasket which combines the benefits of soft cut materials with the advantages of seal integrity associated with metallic gaskets
