Abstract: This invention relates to an improved rod packing characterized by a single segmented ring having three circumferentially-grooved 120.degree. segments held together in abutted end-to-end circle-forming relation by an endless spring seated in the groove, a circumferentially-grooved chordal segment formed integral with each ring-forming segment on one face thereof, three circumferentially-grooved generally wedge-shaped segments adapted to bridge the joint between the ring segments while cooperating with the chordal segments to define a second ring in face-to-face relation to the first of essentially the same dimensions, and another endless spring holding the elements of the second ring in circle-forming relation seated in the grooves thereof.
