Description
Castrol Hyspin HVI 46
Product Description
Castrol Hyspin HVI 46 is a premium high viscosity index (HVI), zinc-free (ashless) anti-wear hydraulic oil designed for hydraulic and circulating systems operating across a wide temperature range. It is formulated with shear-stable viscosity modifiers to maintain consistent performance under prolonged service conditions and varying operating temperatures.
Hyspin HVI 46 delivers excellent wear protection, oxidation resistance, corrosion protection, water separation, and fine filtration performance. It is particularly suitable for outdoor hydraulic equipment exposed to cold starts and continuous high-temperature operation, as well as precision indoor manufacturing systems.
