## 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 Wellringdichtung mit Graphitauflage und Innenbördel (1.4571), Profil WD20, WS 1.4571/3803, Dichtungsdicke 3 mm, Rev. 01 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:
