Grease Suitable for Natural Gas Service

Grease Suitable for Natural Gas Service

Grease Suitable for Natural Gas Service

(OP)
Does anyone have some ideas about what grease should be used on ball (floating or trunnion) valves when exposed to natural gas?  I understand many tradition greases will react and harden over time, which increases valve torque and likelihood of seat leakage.
