larger image Conoco FR Hydraulic Fluid is an invert-emulsion (water-in-oil) type fire-resistant hydraulic fluid developed for use in hydraulic systems operating at 2000 to 3000 psi in areas subject to fire hazards. It combines the benefits of an oil-based hydraulic fluid with the fire-resistant properties of water. It is approved by the MSHA for use in underground mining equipment. FR Hydraulic Fluid is formulated with high-quality paraffinic base oils, 40% water and a special emulsifier than produces a stable, homogeneous invert emulsion. It is fortified with antiwear additives, rust and corrosion inhibitors, and a biocide. The outer oil film lubricates and protects hydraulic system components against rust, corrosion and wear. The inner water core provides fire resistance in case of ignition of a fluid leak. The biocide helps prevent bacterial growth in system reservoirs. FR Hydraulic Fluid is compatible with most hydraulic pump types, including vane, piston and gear pumps. It is safe to use with packing and seal materials commonly used in conventional oil systems. Avoid cork shaft seals and butyl seals and packing. Proper hydraulic system preparation is necessary when changing over from a conventional petroleum oil or water-glycol fluid. Caution: FR Hydraulic Fluid should not be used in systems where operating temperatures exceed 175°F (79°C). This product contains water and should not be stored at temperatures over 130°F (54°C). Water content must be maintained at a minimum of 40% (by volume) to ensure adequate fire resistance.
