ABSTRACT:
A packing system, for providing a seal around a valve stem, including a packing cartridge and a bushing. The packing cartridge includes a sleeve which has a tapered central passage. The sleeve also has external male threads and a hex head. Packing material is attached to the tapered central passage of the sleeve using an adhesive. The sleeve together with the packing material form the packing cartridge. The bushing also has a tapered central passage. The packing of the present invention is applied by sliding the bushing around the valve stem, and then sliding the packing cartridge around the valve stem. Once the bushing is seated in the stuffing-box of the valve, the sleeve is tightened down into the stuffing-box, thus squeezing the packing material and creating a seal around the valve stem.
