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, silver layer, Profile KD01-KD10-KD20-KD30, WS 1.4828/silber, thickness 4,8 mm, Rev. 03 can be assigned to the categorie 0 : "Custom". Therefore, the following friction coefficients can be considered:
