ISO VG 46 Hydraulic Oil Specifications

What is ISO VG 46 Hydraulic Oil?

Armor Lubricants Hydraulic Oil Specifications

ISO VG 46 Hydraulic Oil is a premium, environmentally conscious hydraulic fluid. Its synthetic, biodegradable ester base and advanced additive package ensure exceptional anti-wear, extreme pressure, thermal stability, corrosion resistance, and oxidation resistance. The fluid’s naturally high VI and low pour point provide a wide operating temperature range.

AW 46 Hydraulic Oil is the ideal choice for applications where environmental impact is a major concern.  It excels in situations where accidental fluid leakage could contaminate the environment or surface water.

Key Application Areas Include:

  • Industrial: Wastewater treatment plants, reservoirs, waterways, and parkland.
  • Forestry and Marine: Drilling and logging equipment, dredgers, river sluices, agricultural machinery, and shipboard systems (e.g., bow thrusters, propeller systems, deck machinery).

AW 46 Hydraulic Oil Applications

ISO AW 46 Hydraulic Oil is optimally designed for use within the power and energy sector, particularly suited for wind turbine applications. Special handling guidelines apply to the Hydraulic Oil series to maintain its efficacy.

While it is compatible with mineral oil-based hydraulic fluids, mixing the two can significantly reduce its biodegradability. It is advisable to conduct compatibility tests prior to mixing. To ensure optimal performance, the presence of residual mineral oil should be minimized.

Coating systems should utilize a two-part epoxy to maintain integrity. Contact with metals such as zinc and tin are discouraged due to potential adverse reactions. Users should also be aware that the cleaning properties of this series may release substantial amounts of debris, potentially leading to a reduced lifespan for filters.


The hydraulic oil we offer is engineered to meet stringent industry standards, ensuring superior performance and environmental safety. Below is a detailed overview of its compliance with international and national specifications: Meets the requirements of:

  • ISO 46 L-HEES (ISO 15380, 2011)

Health and Safety Guidelines for Handling Hydraulic Fluid

Hydraulic fluid formulated from highly refined mineral oils and specific additives; it is not considered toxic under normal usage conditions. However, caution should always be exercised when handling any type of lubricant to minimize health risks.

Safety Recommendations:

  • Skin Contact Avoidance: Direct contact with the skin should be avoided to prevent irritation or other dermal concerns. Using protective gloves and washing hands after handling can mitigate risks.
  • Splash Prevention: Take measures to avoid splashing during use to reduce the risk of eye or skin exposure and potential staining or damage to surrounding materials.
  • Fire Safety: Maintain a safe distance from flammable materials to prevent accidental ignition, as lubricants can be combustible under certain conditions.
  • Storage Instructions: Store the lubricant in a covered area, away from any potential environmental pollutants and in a manner that reduces the risk of accidental spillage or leakage.
  • Environmental Protection: Dispose of used oil responsibly. It should not be discharged into drains, watercourses, or onto the soil to prevent environmental contamination. Follow local regulations regarding the disposal of hazardous materials to ensure compliance and environmental stewardship.

Adhering to these guidelines will help ensure safe handling and contribute to workplace safety and environmental conservation.
