United Hydro Vesta Hydraulic Oils HX offer state-of-the-art formulations that produce a line of universal anti-wear long-life hydraulic oils having all the wear preventive characteristics required for the most severe of applications, including high-pressure vane pumps. It is formulated with ashless and zinc-free additive packages that make it suitable for pump-containing steel-on-bronze lubrication surfaces and silver plates.

United Hydro Vesta Hydraulic Oils HX possess excellent thermal and oxidative stability thanks to its fully synthetic content. They can function for much longer operational periods without forming sludge, varnish or other degradation products, which adversely affect the operation and performance of today’s modern hydraulic system components and filtration systems.

United Hydro Vesta Hydraulic Oils HX have excellent hydrolytic stability, providing protection to all hydraulic system components even in the presence of moisture. Additives used in some hydraulic oils break down under conditions of high temperature and moisture to form acids that can attack copper and its alloys such as brass and bronze.
