AW Clutch Brake Hydraulic Oil

Product code : (HAW)

  • Excellent anti-wear properties protect critical components for long life
  • Rapid air-release properties help prevent foam for reliable operation
  • Oxidation inhibitors maximize fluid life while fighting sludge and varnish for clean, efficient operation
  • Provides superior filterability
  • Helps condition seals and prevent leaks

AW Clutch Brake Hydraulic Oil

Anti-wear (AW) oil formulated to provide excellent wear protection for hydraulic pumps, motors and other components. Resists oxidation in the presence of heat and dissipates foam for reliable protection and performance. Tested and approved by Ortlinghaus* for use in its hydraulic applications.


  • Formulated with high-quality conventional base oils and an advanced anti-wear additive system.
  • Protects hydraulic motors, pumps, valves and other critical components against wear for excellent performance and long life.


  • Formulated with oxidation inhibitors that resist the formation of acids and sludge.
  • Resists chemical breakdown in the presence of elevated heat to help keep components clean and functioning properly.


  • Completely eliminates foam in industry-standard testing (ASTM D892), which translates into formation of a strong, reliable oil film for excellent protection and efficient operation.
