CHEMPOL 5065 Ashless Rust & Oxidation Inhibitor


CHEMPOL 5065 ashless rust and oxidation (R & O) inhibitor is fully formulated for high-quality turbine rust and oxidation hydraulic fluids. It provides extended oxidation life and is compatible with other additives commonly used in hydraulic fluids. It also provides excellent rust control, demulsibility and filterability. These features all add up to longer fluid life and reduced system maintenance
