ISO 15 HVI Hydraulic Oils have a thickness that is similar to SAE 5W at operating temperature. High Viscosity Index hydraulic oils, also called Multi-Viscosity Hydraulic Fluids, are formulated to maintain their ideal viscosity, or thickness, over an extreme range of temperatures. The wider the temperature range, the higher the viscosity index number.
We carry ISO VG 15 HVI hydraulic fluid from top names like Mobil, Kendall, Chevron, and Sunoco.
