MARK OILS 550 Industrial Hydraulic Oil

MARK OILS 550 Is a premium quality, high viscosity index, ashless hydraulic oil made from selected hydro-treated base stocks,a highly shear stable viscosity modifier and an advanced anti-wear additive.  In addition they contain a fluorescent dye to allow for easy identification in daytime or under UV light in dark conditions.

MARK OILS 550 Is designed for use in hydraulic systems subjected to wide range of ambient temperatures such as in marine environments, mining, construction and agricultural equipment and forestry.

MARK OILS 550 Is recommended for use in all types of hydraulic systems using vane, piston or gear pumps, air-line lubricators, vacuum pumps, lightly loaded gear sets and bearings (such as headstocks, windmill gears) and hydraulic hoists and jacks.

MARK OILS 550 Can be used in Marine applications which includes deck equipment, steering gear and bow & stern thrusters.

MARK OILS 550 Is recommended for use in cane harvester hydraulic systems and in Dingo equipment.
