Syndustrial®R&O Oil

Synthetic Diester Lubricant

Phillips 66®Syndustrial R&O Oil is a premium quality, synthetic diester lubricant developed for use in air compressors and select steam turbines operating under severe-service conditions, and in moisture-free environments. It is particularly recommended for use in applications where operating conditions may be unfavorable or too severe for conventional mineral oil-based lubricants.

Features & Benefits

• Excellent resistance to thermal breakdown at high temperatures

• Excellent oxidation resistance to minimize sludge and varnish formation

• Protects against wear

• Protects against rust and corrosion

• Natural detergency

• Excellent low-temperature properties

• Extended service intervals compared with conventional mineral oil-based lubricants

Applications

• Reciprocating air compressors

• Select rotary air compressors operating in a dry environment

• Elliott ring-oiled turbines, where a synthetic diester turbine oil is specified

• Circulating systems requiring a synthetic diester lubricant

• Steam turbines where the manufacturer specifi es a synthetic diester lubricant

• Plain and rolling-element bearings operating at very high or very low temperatures

• Industrial equipment operating over a wide temperature range where an inhibited mineral oil is recommended
