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).

CAUTION

Do not lubricate graphite packing. Graphite packing is self-lubricated. Additional lubrication may result in slip-stick

movement of the valve.
