HY VI III ISO-VG-68

It refers to the viscosity grade (VG) of the Hydraulic oil. ISO VG 68 is international standards organization (ISO) classification that indicates the thickness of the fluid.

Common applications of this Hydraulic oil are: hydraulic systems, gearboxes, circulating systems, and other industrial machinery where moderate viscosity oils are required. 

Specifically, it’s often employed in equipment operating under moderate to heavy loads and in moderate temperature environments.

As compared to other Hydraulic oils like ISO VG 32 OR VG 46, this oil possesses high viscosity and tolerate heavier loads and operating conditions. However, for heavy-duty systems with very high loads, Hydraulic oils with higher viscosity grades like 220 or 320 are more suitable.

ISO VG 68 Hydraulic oil provides effective lubrication at high temperature and heavy loads. It prevents the system from corrosion and ensures uninterrupted functioning of hydraulic systems. 

Yes, ISO VG 68 Hydraulic oil can be used in high-pressure systems. However, it is crucial to consult the manufacturer’s guidelines before using this fluid in a particular system.

Yes indeed, ISO VG 68 Hydraulic oil is biodegradable and environmentally friendly.

The frequency of oil changes for ISO VG 68 oil depends on various factors, including equipment operating conditions, environmental contaminants, and manufacturer recommendations. Regular oil analysis and monitoring can help determine the optimal change intervals.
