General guidance on cross-referencing hydraulic fluids

General guidance on cross-referencing hydraulic fluids.

1. Consult Manufacturer Documentation: Many hydraulic equipment manufacturers provide recommendations for compatible hydraulic fluids in their equipment manuals or maintenance guides. These recommendations are based on the equipment's specifications and requirements.

2. Fluid Properties: When cross-referencing hydraulic fluids, it's important to consider the properties of the fluid, such as viscosity, viscosity index, additives, and compatibility with seals and materials in the hydraulic system. Match these properties as closely as possible when selecting an alternative fluid.

3. ISO Viscosity Grades: Hydraulic fluids are often classified by their ISO viscosity grades. For example, ISO VG 32, ISO VG 46, ISO VG 68, etc. Look for fluids with similar ISO viscosity grades when searching for alternatives.

4. Manufacturer Cross-Reference Guides: Some hydraulic fluid manufacturers provide cross-reference guides or compatibility charts on their websites or product documentation. These guides can help you find equivalent fluids from different brands.

5. Consult with Experts: If you're unsure about which hydraulic fluid to use as a replacement, consider consulting with hydraulic system engineers, fluid suppliers, or equipment manufacturers for recommendations based on your specific application.

Remember that ensuring compatibility is crucial to prevent damage to your hydraulic system and maintain optimal performance. If you have specific brands or types of hydraulic fluids in mind that you need to follow the following cross-reference chart.

The following chart may be used to help determine the proper ISO grade hydraulic fluid to use with your system by referencing the manufacturer and model pump used in your equipment or fluid powered system. In the chart below, the ISO grade (32, 46, 68) fluid to be used should fall within the range of the optimum cSt listed in the right-hand column.
