KLINGER®Maxiprofile 109

Characteristic & main applications

The Maxiprofile is a composite gasket, which utilises a serrated metal core with a soft facing material. The metal core is machined on each contact face with concentric serrations to a specific profile which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads.

Standard core design is parallel which offers the advantage of even stress distribution across the gasket face. Convex Maxiprofiles are also available which have a reduced depth of grooves towards the profile centre. This type of profile ensures a high seating stress in the middle of the profile and is effective for low bolt load applications.

The result is a gasket, which combines the benefits of soft cut materials with the advantages of seal integrity associated with metallic gaskets. The Maxiprofile type 109 exhibit excellent results, particularly where high pressures, temperatures and therefore, high bolt loads are to be controlled.

A variety of surface coatings can be applied to service high temperature, pressure or corrosive media applications. Temperature range from cryogenic to 1000°C with a wide chemical resistance.
