Abstract
Non-flammable hydraulic fluids which are particularly useful for replacing existing hydraulic fluids in hydraulic systems employing acrylonitrile-butadiene rubber and fluoroelastomer seals are disclosed. The non-flammable hydraulic fluids of the present invention comprise a fluorinated chlorotrifluoroethylene oil, a refined naphthenic oil, a phenolic antioxidant, a sulfur corrosion inhibitor, a metal deactivator, and an aliphatic ester. The fluorinated chlorotrifluoroethylene oil is present in an amount of at least about 75% by volume of the hydraulic fluid. In addition to being non-flammable, such hydraulic fluids are compatible with both the seals and brass components which contact the hydraulic fluid in hydraulic systems.
