Wet Gas Compressor Oil

Compressor Oil
Phillips 66®Wet Gas Compressor Oil is a high-quality lubricant developed for the lubrication of oil-flooded rotary compressors in natural gas service. It also is recommended for cylinder lubrication of reciprocating compressors in natural gas service. It is specially formulated to minimize the effects of gas dilution and oil absorption and to resist wash-off in compressors handling “wet” gas (natural gas containing liquid hydrocarbons and/or water).

Features & Benefits

• Excellent oxidation resistance and thermal stability

• Resists lubricant “wash-off”

• Formulated to minimize the effects of gas dilution and oil absorption

• Good wear protection

• Protects against rust and corrosion

• Good foam resistance


• Oil-flooded rotary screw, rotary lobe and rotary vane compressors handling wet natural gas

• Industrial reciprocating compressors pumping wet natural gas

• Reciprocating compressors commonly found in remote gas gathering stations
