Technical Details & Test Data
- Product Highlights
- Flammability Properties : FRH-200 is classified as a less hazardous hydraulic fluid. The fluid exhibits no flash or fire point. In an extreme heat situation for a prolonged period of time, water can boil out of the fluid.
- Wear Protection : FRH-200 is designed to pass the ASTM D2882, 2000 psi pump test using a Vickers V 104C pump. These fluids meet the U.S. Steel requirement #171 for 2000 psi fluids. Many years of service can be expected under typical operating conditions using FRH-200.
- Corrosion Protection : FRH-200 is well inhibited against liquid phase corrosion of iron, steel, and copper alloys. In addition, it has a very effective vapor phase rust inhibitor to prevent corrosion of reservoirs and components above the liquid level. However, systems utilizing solder, tin, lead, zinc, magnesium or cadmium should not use water-glycol fluids since such fluids may be corrosive to these metals.
- Compatible Paints : Water-glycol fluids are not compatible with most paints, enamels or varnishes. Prior to fluid installation the insides of reservoirs and accumulators should be stripped of paints, unless the paints are known to be compatible with water-glycol fluids. The following companies represent a partial list of those who manufacture compatible paints:
- Rust-Oleum Corporation - Evanston, IL
- The Glidden Company - Cleveland, OH
- Pittsburgh Plate Glass Company - Pittsburgh, PA
- Coast Paint & Lacquer Division - Houston, TX
- Sherwin-Williams Company - Cleveland, OH
- Steelcoat Manufacturing Company - St. Louis, MO
- Compatibility With Other Hydraulic Fluids : FRH-200 is compatible with all known major brands of hydraulic fluids, in any proportion. They are not compatible with other types of hydraulic fluids such as mineral oil, water-oil emulsions or synthetic phosphate esters, and should not be mixed with these products.
- Compatible Pipe Joint Compounds : If a system has been assembled with any good grade pipe joint compound, it will operate satisfactorily with FRH-200 hydraulic fluid. New installations or pipes replaced during maintenance operations should be sealed with Teflon ribbon (available from any hydraulic fitting supply house).
- Viscosity Index : FRH-200 provides excellent efficiency through an exceptionally high viscosity index which is stable under the high shearing stresses of hydraulic systems.
- Shear Stability : Since viscosity of a hydraulic fluid is of utmost importance in determining the pump volumetric efficiency, it is essential that the fluid have a high resistance to shear. Some fire-resistant fluids decrease in viscosity as a result of the shearing action of pumps and valves under continuous use. FRH-200 does not shear under these conditions.
Packaging & Availability
- Packing Compatibility
Experience indicates nitrile (Buna-N) and neoprene seals and packings, normally used for petroleum oils are satisfactory for use with FRH-200. Silicone, butyl, and ethylene-propylene are also suitable materials. Do not use asbestos, leather or cork impregnated materials.
Storage & Handling
- Storage Stability
FRH-200 will withstand long periods of storage under varying temperatures. Freezing and thawing has no ill effects on the properties of this fluid.
