## Friction coefficient µG

The friction coefficient between gasket and flange surface was determined for different types of gasket materials in an ESA research project.

 The gasket Grooved gasket, SIGRAFLEX® MF layer, Profile KD01-KD10-KD20-KD30, WS 1.4571/3871, thickness 5 mm, Rev. 01 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:
