Sigma Hydraulic oil series are formulated from high base stocks and premium grade hydraulic oil additives package to provide excellent performance in most of the Hydraulic applications. They are resistant to oxidation and rust. These fluids have an inherently high viscosity index which is very much stable. Soil Hydraulic series are extremely efficient for Hydraulic systems operating in low, high or varying ambient temperature.
This series are suitable for hydraulic systems of all designs. They are equally usable in industrial, marine and mobile services which operate at low, high or rapidly changing ambient temperature.
