Environmentally-friendly oils

Green A/W Oils anti-wear hydraulic oils are for use in high-pressure pumps and gears in environmentally sensitive areas. They are aromatic-free, inherently biodegradable and will pass the U.S. Coast Guard static sheen test. They are nontoxic to aquatic life. They offer high thermal and oxidative stability, exceeding 15,000 hr D 943 TOST Life. Four grades — 22, 32, 46, and 68 — have viscosity indexes of 110, 106, 104, and 102, respectively.

Fire-resistant fluid

Cosmolubric B-230 is a vegetable oil-derived fluid formulated with additives to enhance corrosion protection, metal passivation and oxidative inhibition. It is preferred over mineral oil-based fluids because it resists ignition and is less flammable in the event of a hydraulic line rupture. It is readily biodegradable, approved by Factory Mutual as a less hazardous fluid, and listed as BioPreferred by the USDA.
