Date Apr. 16, 1992.Seal for gas carrying lines, of an inorganic material of a yield stress and viscosity at the operating temperature that are sufficiently high to counteract leakage of the glass through the opening as a consequence of its own weight and the pressure gradient and fitted between at least two parts which must be able to move relative to one another characterized in that the seal is constructed to permit a movement in axial direction.
