Abstract
An annular seal element is configured to seal off a pressurized region filled with a fluid. The annular seal element has one end face which is pressed onto a contact surface of a piston. The end face is formed with a sealing contour in such a way that the sealing contour is elastically deformable on the contact surface by the pressure exerted.
