Ultra-Clean Multipurpose R&O Oil

Rust & Oxidation-Inhibited, Anti-Wear Circulating Oil

Phillips 66®Ultra-Clean Multipurpose R&O Oil is a rust and oxidation (R&O)- inhibited, anti-wear circulating oil specially developed for use in industrial equipment that requires an ultra-clean fluid. It provides the same performance features as Multipurpose R&O Oil plus the added benefit of fine filtration to a typical ISO Cleanliness Code of 17/15/11, for use in circulating systems with tight tolerances where particle contamination can cause operational problems.

Features & Benefits

• Good oxidation resistance to minimize sludge and varnish formation

• Mild wear protection

• Protects against rust and corrosion

• Excellent water-separating properties

• Low carbon-forming tendency for use in centrifugal air compressors

• Good foam resistance

• Meets ISO Cleanliness Code rating of 17/15/11


• Circulating systems where fluid cleanliness is critical

• Centrifugal air compressors

• Steam turbines and hydroelectric turbines, both direct-drive and those with gear drives

• Lightly loaded enclosed industrial gear drives where the OEM specifies a R&O-type oil (ISO VG 68, 100)

• Electric motor bearings

• Vacuum pumps and machine tools
