Friction coefficient µ_G

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

The gasket Flachdichtung SIGRAFLEX® Universal Pro, Profil FD01, WS 3865, Dichtungsdicke 2 mm, Rev. 02 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:

Temperature / °C	Friction coefficient
20 °C	0.22
