Syndustrial®Hydraulic Fluid

Synthetic Anti-Wear Hydraulic Fluid

Phillips 66®Syndustrial Hydraulic Fluid is a premium quality, synthetic anti-wear hydraulic fluid specifically developed for use in industrial and mobile equipment operating in environmentally sensitive areas. It is readily biodegradable for reduced environmental impact in case of leaks or spills. Three grades are certified by the FMRC as fire-resistant for use in areas subject to fire hazards, and two grades are approved by the MSHA for use in underground mining equipment.

Features & Benefits

• Fire resistant, with high flash point, fire point, and auto-ignition temperature for reduced risk of fire/explosion (ISO 46, 68, 100)

• Outstanding oxidation resistance and thermal stability at high temperatures

• Excellent wear protection for hydraulic pumps and motors

• Protects against rust and corrosion

• Good low-temperature fluidity

• Non-toxic, non-irritating, and contains no hazardous ingredients

• Readily biodegradable (all grades)

• Fire resistance certified by Factory Mutual Research Corporation (ISO 46, 68, 100)

• MSHA approved (Approval Number 35-A080004, ISO VG 68; Approval Number 30-20-3, ISO VG 100)


• Mobile and stationary equipment operating in environmentally sensitive areas (all grades)

• Hydraulic systems subject to fire hazards and/or extreme heat (ISO VG 46, 68,100)

• Steel mill, foundries, and manufacturing plants (ISO VG 46, 68, 100)

• Underground mining equipment where a fire-resistant, MSHA-approved hydraulic fluid is required (ISO VG 68, 100)
