Syndustrial®PAG Compressor Oil

Synthetic Polyalkylene Glycol-Based Compressor Oil for Natural Gas Service

Phillips 66®Syndustrial PAG Compressor Oil is a premium quality, synthetic lubricant developed for use in centrifugal and oil-flooded rotary screw and rotary vane compressors processing natural gas, carbon dioxide, propane, or other hydrocarbon gases. It is specially formulated to resist hydrocarbon dilution and oil absorption in this type of service.

Features & Benefits

  • Highly resistant to dilution by hydrocarbon gases
  • Resists washout by condensed hydrocarbon liquids
  • Resists absorption into the gas stream and subsequent carryover of the lubricant downstream
  • Outstanding oxidation resistance and thermal stability at high temperatures
  • High viscosity index and low pour point for use over a wide temperature range
  • High film strength for wear protection
  • Protects against rust and corrosion
  • Extended service intervals compared with mineral oil-based lubricants
  • Compatible with commonly used seals, gaskets, and hoses(1)

(1) Note: Syndustrial PAG Compressor Oil is compatible with neoprene, silicone rubber, torlon, vespal and viton, as well as epoxy paints. It is not compatible with oil-based paints or with solvents, such as diesel fuel, kerosene, heptane, methanol, ethylene glycol or triethanolamine.


  • Oil-flooded rotary screw and rotary vane compressors processing natural gas, carbon dioxide, or other hydrocarbon gases
  • Centrifugal compressors processing propane refrigerant, including York centrifugal compressors where York Oil Q (ISO VG 46) or York Oil R (ISO VG 68) is recommended

Note: Syndustrial PAG Compressor Oil is not compatible with petroleum compressor oils. Care should be taken to avoid mixing the two products. When switching over from mineral oil to Syndustrial PAG Compressor Oil, a complete flush, drain, and refill should be performed.

CAUTION: Syndustrial PAG Compressor Oil is not recommended for use in R-134a refrigeration compressors that require a PAG lubricant.
