Zusammenfassung:	The present disclosure relates to a sealing device 20 for a control rod 17, passing through an aperture 15c in a wall 15, wherein the control rod 17 is connected between an actuator 13, placed on one side of the wall, and a controlled entity 9a, placed on the other side of the wall, such that the actuator can control the controlled entity with motion of the control rod. The sealing device 20 includes a packing box 37 through which the control rod 17 passes and a seal 41 which provides a sealing function between the control rod 17 and the packing box 37. The packing box 37 is moveable with the control rod 17 in relation to the wall 15. Wall aperture 15c is sized to allow movement of the control rod 17 within aperture 15c. A flexible member 39 surrounds a portion of control rod 17 and extends between the packing box 37 and the wall 15, in a gastight communication with each. As such, the subject sealing device allows movement of the control rod without compromising the sealing function efficiency thereof.
