## 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 Spiralwound gasket with inner and outer ring, graphite filler, SD10, WS 1.4301/Graphite/St37 coated, thickness 4,9 mm, Rev. 01 can be assigned to the categorie 3 : "Gaskets based on flexible graphite". Therefore, the following friction coefficients can be considered:
