Industrial oil I-8А is refined distillate and residual oils or it’s mixtures without any additives. These oils are used for machines and mechanisms of industrial equipment that does not impose specific requirements to anti-oxidation and anti-corrosion properties of oils. These products can also be used as hydraulic liquids.
