Packing Maintenance

Note
For valves with ENVIRO-SEAL live-loaded packing, see the Fisher instruction manual, ENVIRO-SEAL Packing System for Sliding-Stem
Valves, for packing instructions. For valves with HIGH-SEAL live-loaded packing, see the Fisher instruction manual, HIGH-SEAL
Live-Loaded Packing System, for packing instructions.
For spring-loaded single PTFE V-ring packing, the packing spring maintains a sealing force on the packing. If leakage is
noted around the packing follower, check to be sure the shoulder on the packing follower is touching the bonnet. If
the shoulder is not touching the bonnet, tighten the packing flange nuts until the shoulder is against the bonnet. If
leakage cannot be stopped in this manner, proceed to the Replacing Packing procedure.
