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 Flachdichtung SIGRAFLEX® Universal , Profil FD01, WS 3862, Dichtungsdicke 2 mm, Rev. 00 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:

Temperature / °C Friction coefficient
