A hydraulic control oil belonging to the so-called “stabilised zinc” generation. This anti-wear hydraulic oil features excellent resistance to hydrolysis and thermal alteration. Possesses zinc dithiophosphate-based anti-wear additives and a high viscosity index, enabling it to withstand high temperatures and water. Also possesses chemical stability, and its exceptional anti-corrosive properties support its neutrality to metals and elastomers (compatibility with seals). Features very good shear strength, and possesses a very low pour point.
