Phillips 66® FR Fluid-Glycol is a water-glycol based fire-resistant hydraulic fluid developed for use in industrial hydraulic systems operating in areas subject to fire hazards. It contains sufficient water to snuff out a fire resulting from ignition of a fluid leak. It is suitable for use in hydraulic systems operating at 2,000 to 3,000 psi, and can withstand intermittent pressure spikes up to 5,000 psi.
• Fire-resistant for safety
• Excellent wear protection for hydraulic pumps and motors
• Excellent rust and corrosion protection
• Good foam resistance
• Glycol content protects against freezing
• Compatible with other water-glycol fluids
