Syncon®AW Hydraulic Fluid

Synthetic Anti-Wear Hydraulic Fluid

Phillips 66®Syncon AW Hydraulic Fluid is a premium quality, synthetic anti-wear hydraulic fluid developed for use in industrial and mobile equipment operating 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 hydraulic oils.

Features & Benefits

• Outstanding oxidation resistance and thermal stability at high temperatures

• Outstanding pumpability at low temperatures

• Excellent wear protection for hydraulic pumps and motors

• Protects against rust and corrosion

• Separates rapidly from water

• Good foam resistance

• High dielectric strength

• Compatible with conventional mineral oils and commonly used seals


• Industrial and mobile equipment operating under extreme-temperature conditions

• Automated machine tools

• Bucket trucks (cherry pickers) used for servicing electrical power lines or for tree trimming

• Hydraulic hoists and service station lifts

• Mobile construction equipment

• Chain drives

• Electric motor bearings
