It has no segments—no springs to lose temperand fail, causing gaps that leak pressure and cornersthat score the cylinder. It is made of special ProcessedGrav Iron—wonderfully tough, smooth and permanentlyelastic. A test by a leading air compressor manu-facturer demonstrated that the use ofPacking Rings produced 90 from zero, in two-thirds the timerequired by segmented packing rings—andwith check valve removed, held the pres-sure 331/r!r/r- longer.
