Conoco Wet Gas Compressor Fluid is a high-quality lubricant developed for the lubrication of oil-flooded rotary compressors and for cylinder lubrication in 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).

Wet Gas Compressor Fluid is available in one viscosity grade: ISO 220. It is formulated with high-quality paraffinic base oils and select additives to provide excellent service and protection in gas compression service. It has excellent oxidation resistance and thermal stability at high temperatures to help minimize deposit formation and provide long service life. It protects against rust, corrosion and wear, and is resistant to excessive foaming that can interfere with proper lubrication. An oiliness additive provides good metal-wetting ability to help resist lubricant wash-off.

Wet Gas Compressor Fluid is particularly recommended for use in applications where the gas outlet temperature is well above the condensation point of the gas.
