Product Description

Cosmolubric HF-122 is a Factory Mutual approved high quality synthetic polyol ester hydraulic fluid. Chemically and thermally stable, Cosmolubric HF-122 was designed for long life and dependable performance in areas where a less flammable hydraulic fluid should be used.
Besides having good thermal stability, Cosmolubric HF-122 exhibits a good temperature/viscosity relationship or Viscosity Index. Cosmolubric HF-122 also contains an additive package formulated in the Houghton laboratory and proven in the field, to give the best possible performance, corrosion prtection, metal passivation, hydrolytic stability and oxidation inhibition.


  • Factory Mutual Approved as a fire resistant hydraulic fluid that protects personnel and property from accidental fire and may lower insurance premiums.
  • Hgsh viscosity index allows the fluid to be used at a wide temperature range.
  • Fluid is a GREEN product that is composed of renewable resources.
  • Contains additives to enhance oxidation stability that will extend service life.
  • Provides exxellent lubrication characteristics which extends pump and component life.
  • Hydrolytically stable to resist degradation when water contamination is present.
