hydraulic oils

Today, hydraulic pumps are smaller, more complex, and are required to handle higher flow rates, pressures and temperatures. Oronite has developed solutions to improve the reliability and performance of modern hydraulic equipment for a wide range of applications. Our anti-wear hydraulic oil additives meet the performance standards of the best hydraulic equipment manufacturers in the world.  Besides extensive laboratory testing, our technology development also involves real-world testing, regular exchanges, product validation and approvals with key original equipment manufacturers (OEMs) such as Denison® and Eaton Vickers®.


Oronite additives offer system reliability by using formulations which prevent wear, valve sticking, metal transfer and filterability issues. Our hydraulic oils can handle more demanding duty cycles such as continuous production or continuous service of leased equipment. And you will find that our products provide resistance to higher operating temperatures and can be applied in a wide variety of base oils.
