ABSTRACT:
A screwable cable seal introduction device for employment at sleeves or housings having an introduction sheath onto which a union nut can be screwed. A press sleeve is located in the inside of the introduction sheath, an annular seal composed of sealing material and laterally arranged support rings being deformed with the press sleeve until the required adhesion of the sealing material at the sealing surfaces to be contacted is accomplished. An automatic pressure compensation subsequently occurs, so that no permanent pressure is exerted onto the introduced cable.
