The present invention provides an improved seal cage for maintaining selected spacing between packing seal rings of an injectable sealing compound system. It comprises a pair of flexible elongate rails that are laterally spaced apart by rigid braces which extend between the rails and are held in brace receptacles spaced apart longitudinally of a rail. The rails can be cut to encircle shafts of different circumferences and the braces can be of any desired length. For convenience sake, a seal cage according to the present invention can be provided as kit comprising, for example, rails having brace receptacles of different heights, braces of different lengths, and master links for connecting sections of seal cage to produce longer seal cages.
