Its versatility makes it a common choice for maintenance departments seeking a reliable, all-purpose hydraulic fluid that meets international specifications without the premium price tag of high-performance synthetics. Understanding ISO 22 and Its Place in Hydraulic Standards The designation "ISO 22" refers to a hydraulic oil viscosity grade defined by the ISO 4406 standard, which categorizes fluids based on their kinematic viscosity at 40°C.
ISO 22 Hydraulic Oil Application Overview and Key Uses
Standard mineral-based ISO 22 is generally compatible with most metals used in hydraulic pumps and cylinders, but it can be aggressive towards certain types of seals and paints found in older equipment. This mineral-based formulation delivers reliable performance for general industrial machinery, providing a balance between lubrication, thermal stability, and compatibility with common seal materials.
Choosing ISO 22 is often a calculated decision for systems designed to run efficiently within its specific temperature and load parameters. Conversely, higher grades such as ISO 32 or ISO 46 offer increased viscosity, which is necessary for systems under high pressure or operating in hotter environments.
