Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, and cooling in the hydraulic system. HL hydraulic oil is made of neutral base oil with high refining depth, plus anti-oxidation and anti-rust additives. HL hydraulic oil can be divided into six grades of 15, 22, 32, 46, 68 and 100 according to the kinematic viscosity at 40°C.
