Syncon®R&O Oil (ISO VG 100-680)

ISO VG 100-680

Phillips 66®Syncon R&O Oil (ISO VG 100-680) is a premium quality, synthetic, rust and oxidation (R&O)-inhibited circulating oil developed for use in circulating systems, lightly loaded enclosed gear drives, and other industrial equipment operating under severe-service conditions or at extreme temperatures. It is particularly recommended for use in applications where operating conditions may be unfavorable or too severe for conventional mineral oil-based circulating oils.

Features & Benefits

• Outstanding resistance to thermal breakdown at high temperatures

• Outstanding oxidation resistance to minimize deposit and varnish formation

• Protects against wear

• Protects against rust and corrosion

• Good water-separating properties

• Good foam resistance

• Excellent low-temperature fluidity

• Extended service intervals compared with mineral oil-based lubricants

• Compatible with mineral oil-based lubricants(1)

(1)Note: For optimum performance, the mineral oil lubricant should be drained before using Syncon R&O Oil. Mixing the two products can reduce the effectiveness and performance advantages normally gained by using Syncon R&O Oil.


Applications

• Plain and rolling-element bearings operating at very high or very low temperatures, and sealed-for-life bearings

• Lightly to moderately loaded enclosed industrial gear drives that do not require a compounded or extreme-pressure (EP) gear lubricant

• Circulating systems of paper machine dryer sections and calender stacks

• Industrial blowers

• Industrial worm gear drives with bronze-on-steel gears

• Reciprocating air compressors where the manufacturer specifies a PAO-based lubricant (ISO VG 100 or 150, typically)

• Lubrication of the upper cylinders of gas compressors handling natural gas or process gas (ISO VG 150 or 220, typically)

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