## 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 Spiral-wound gasket with PTFE filler, WS 1.4541/7110/St33 coated, IDT style SD10, LE, Gasket thickness 5.2 mm, Rev. 01 can be assigned to the categorie 2 : "Gaskets based on filled PTFE". Therefore, the following friction coefficients can be considered:
