Synthetic AW Seal-Swell Hydraulic Oil

  • Base Oil Technology: Synthetic
  • Viscosity Range: ISO 32
  • Viscosity Index: 223

AMSOIL Industrial Synthetic AW Seal-Swell Hydraulic Oil is specifically formulated to replace competitors’ ISO 32 hydraulic oils that over-swelled system seals over time, whether intentionally or not. Hydraulic oils that exhibit normal industry accepted seal-swell properties are generally unable to replace oils that swell seals due to potential leaks.


  • Fights wear on pumps, motors and valves for long life.
  • Inhibits oxidation and helps resist chemical breakdown in the presence of heat for maximum fluid life.
  • Remains fluid in extreme cold for excellent protection and energy efficiency.
  • Provides excellent performance in industry-standard foam testing for reliable operation.
