Packing Lubrication

WARNING
To avoid personal injury or property damage resulting from fire or explosion, do not lubricate packing used in oxygen

CAUTION
Do not lubricate graphite packing. Graphite packing is self-lubricated. Additional lubrication may result in slip-stick
movement of the valve.

ENVIRO‐SEAL or HIGH‐SEAL packing does not require lubrication.
