STUFFING BOX MAINTENANCE PROCEDURE
Routine maintenance of the stuffing box consists of tightening the packing gland periodically. If leakage around the
stuffing box is discovered, first tighten the hex-nuts on the gland follower (more than 2/3 compression) as this may
reduce packing life. If the leakage still persists, replace the packing according to the following procedure. (For
clarity, the actuator and bracket are not shown in the following diagrams. It is not necessary to remove the actuator
or bracket before performing this procedure).
11.1 In order to gain access to the packing, remove the gland follower and slide it up to the actuator. See the diagram
below:
