Note
Whenever a gasket seal is disturbed by removing or shifting gasketed parts, install a new gasket upon reassembly. This is necessary
to ensure a good gasket seal because the used gasket may not seal properly.

Packing Lubrication
CAUTION
Do not lubricate graphite packing. Graphite packing is self-lubricated. Additional lubrication may result in slip-stick
movement of the valve.
Note
ENVIRO‐SEAL or HIGH‐SEAL packing does not require lubrication.
WARNING
To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen
service or in processes with temperatures over 260_C (500_F).
If a lubricator or lubricator/isolating valve (figure 3) is provided for PTFE/composition or other packings that require
lubrication, it will be installed in place of the pipe plug (key 14, figure 21). Use a good quality silicon‐base lubricant. Do
not lubricate packing used in oxygen service or in processes with temperatures over 260_C (500_F). To operate the
lubricator, simply turn the cap screw clockwise to force the lubricant into the packing box. The lubricator/isolating
valve operates the same way, except open the isolating valve before turning the cap screw and then close the isolating
valve after lubrication is completed.
