UCON™ anhydrous hydraulic fluids provide the lubricity and performance required of industrial hydraulic fluids that must operate over wide temperature ranges. Excellent low-temperature properties permit year-round outdoor use. They are resistant to oxidation and thermal degradation as well as to sludge or varnish formation. UCON anhydrous hydraulic fluids have high viscosity indices that are unaffected by high rates of shear.

In the U.S. UCON Trident hydraulic fluids are sold solely through American Chemical Technologies.
