## 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® Hochdruck Pro mit Innen- und Außenbördel, Profil FD30, WS 3888 DB, 1.4571, 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:
