Addition of this colouring additive to an hydraulic oil gives it a blue colour. Don’t use blue concentrate for aqueous solutions. The proportions may change, according to the requirement from 0.2 to 1% in the hydraulic oil. These features allow:
– avoiding a confusion with motor oil
– a quicker detection of possible leakages
– an easy identification of the lubricant
– an easy reading of the lubricant gauge level
