HYDRO SAFE ® OIL DIVISION INC. markets environmentally friendly hydraulic oil to industry with ISO Grades 32, 46, 46FR, and 68FR. Fluids are readily and totally biodegradable, and non-toxic. Base fluid is canola (rapeseed) oil, a renewable resource.

Hydro Safe ® is a vegetable base hydraulic fluid formulated to meet the demand for biodegradable hydraulic oils. Hydro Safe ® offers excellent antiwear performance in a wide array of hydraulic components, and can be used as a superior replacement for conventional petroleum oil. It exhibits excellent thermal and oxidative properties when compared to other vegetable-derived products. Formulated from canola (rapeseed) oil, and containing biodegradable, non-toxic chemical additives, Hydro Safe ® is designed to minimize environmental impact and have low environmental persistence. Its high viscosity index (VI) allows outdoor operations in winter and summer without the need for fluid changes or equipment modifications.

Viscosity Index ASTM D-567, ASA Z11.45 is an empirical number indicating the rate of change in viscosity of an oil within a given temperature range. A low viscosity index signifies a relatively large change in viscosity with oil temperature, while a high viscosity index shows a relatively small change in viscosity with oil temperature changes, providing viscosity consistency and stability. Viscosity Index cannot be used to measure any other quality of an oil. Hydro Safe ® is formulated to provide a long life cycle as documented by the long Bomb Life, as indicated below, before oxidation occurs.

The fluid is totally biodegradable, and exceeds the government criteria of being "readily biodegradable". Readily biodegradable is defined as an attribute of products that have a natural ability to biodegrade quickly and completely. Once the fluid is leaked into the ground, it has the ability of substance to be digested or consumed by naturally occurring microorganisms present in water, air and soil systems. Complete biodegradability is the conversion of a substance to carbon dioxide and water.

Hydro Safe® ISO VG-46 FR has been Factory Mutual Specification Tested. Hydro Safe® ISO VG-68 FR is approved and labeled by Factory Mutual as being " Fire Resistive Fluid." We are ISO 9002 CERTIFIED. Learn more on our Frequently Asked Questions page.
