KLINGER®Graphite Laminate MLX

The graphite gasket with a premium multilayer structure.

This gasket has a multilayer structure consisting of high-purity graphite foils (‹ 99 %) and smooth stainless-steel foils. Testing confirms a 6X increase in rigidity/handleability compared to conventional foil reinforced graphite gaskets. In a special process several layers of graphite and stainless-steel foils are joined together without using any adhesives. A special impregnation ensures the improved sealing performance and excellent handling.

Basis composition

Expanded graphite with 0.05 mm thick smooth stainless-steel foils.

Areas of application

Klinger MLX is suitable for extreme conditions, especially for high pressure applications, high temperatures and high compressive stresses.

Function and durability

The performance and service life of KLINGER gaskets depend to a large extent on proper storage and fitting - factors beyond the manufactor’s control. We can, however, vouch for the excellent quality of our products. With this in mind, please also take note of our installation manual.
