A seal element of a face seal device for sealing a rotary component relative to a stationary component, includes a pair of mounting portions spaced apart from each other and a bellows portion connected with and extending between the mounting portions. One of the mounting portions serves for non-rotational mounting on the rotary component and the other for mounting a seal ring thereon. At least the surfaces of the mounting and bellows portions which are subjected to a medium which is to be sealed are formed of a synthetic material essentially resistant to the medium. The one mounting portion includes at least a single screw bore essentially radially extending therethrough. A screw pin made of a ceramic material is inserted in the screw bore for clamping the mounting portion relative to the rotary component.
