A multipart packing ring for sealing a piston rod of a compressor includes ring segments and sealing segments which are alternatingly arranged to form a ring. The ring segments include a curved main part and an axial shoulder and the sealing segments include a curved main part and an axial projection. The circumferential ends of the main part of the ring segments and the circumferential ends of the axial projection of the sealing elements face one another and define first wear gaps there-between.
