We utilize the highest quality Zinc anti-wear technology along with the best water separation additives available. While most major oil companies, hydraulic oils contain less than 350ppm of zinc, our hydraulic oils contain 750ppm of zinc. This extra Zinc is proven to help reduce wear rates in hydraulic systems. Alpha Premium Hydraulic Oils are specially formulated with additives that are gentle to yellow metal parts such as bronze, brass, and copper. They feature excellent resistance to wear, foam, rust, oxidation, and harmful emulsions with water.

Alpha Hydraulic Oils utilize the highest quality zinc anti-wear technology available. While most oils contain less than 350 ppm of zinc, our hydraulic oils all contain 750 ppm of zinc. Extra zinc has been proven to help reduce wear rates in hydraulic systems. These oils are recommended for all industrial hydraulic systems using gear, vane, axial piston, and radial piston designs. They feature excellent resistance to wear, foam, rust, oxidation, and harmful emulsions with water.
Alpha Premium Hydraulic Oils are formulated with additives that are gentle to yellow metal parts such as bronze, brass, or copper. They resist acid formation under high temperatures. Properly maintained and filtered systems will remain free of sludge and varnish.
