If the packing is relatively new and tight on the stem, and if tightening the packing flange nuts does not stop the
leakage, the valve stem may be worn or nicked so that a seal cannot be made. The surface finish of a valve stem is
critical for making a good packing seal. If the leakage comes from the outside diameter of the packing, the leakage
may be caused by nicks or scratches around the packing box wall. If performing any of the following procedures,
inspect the valve stem and packing box wall for nicks and scratches.

An illustration of a HIGH‐SEAL live‐loaded packing system is shown in figure 6. Illustrations of ENVIRO‐SEAL live‐loaded
packing systems are shown in figures 7, 8, and 9.
