FR Fluid-Glycol

Water-Glycol Based Fire-Resistant Hydraulic Fluid

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.

Features & Benefits

• 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

Applications

Hydraulic systems on equipment operating in areas subject to fire hazards, such as:

• Steel and aluminum mills

• Molding and metal die casting machinery

• Welding machines

• Foundries

• Furnace charging equipment

• Open hearth and basic oxygen furnace (B.O.F.) equipment

• Power transmission plants
