Reolube HYD® 68 is a fire-resistant hydraulic fluid for general industrial applications based on a tri-ayl phosphate. It is classified as an HFDR fluid according to ISO No. 6743/4. Reolube HYD 68 fluid resists ignition under all but the most severe conditions and, even if ignited, will not continue to support combustion once the source of ignition is removed. It has been formulated to provide corrosion protection for both ferrous and non-ferrous metals, while the excellent thermal and oxidation stability will be of value in applications that necessitate high temperatures. All Reolube Hyd fluids have been found to pass the spray test of the United States Factory Mutual Research organisaiton.
