Product Description
Castrol HYSPIN AWH 68 is a premium ISO VG 68 high viscosity index (HVI) anti-wear hydraulic oil designed for severe-duty hydraulic systems, injection moulding machines, earthmoving equipment, agricultural machinery, marine hydraulics, machine tools, and industrial hydraulic applications operating under wide temperature variations and high pressures. This zinc-containing HVLP hydraulic fluid provides excellent pump protection, superior wear resistance, thermal stability, and reliable performance in modern hydraulic equipment.
Castrol HYSPIN AWH 68 is formulated with high-quality mineral base oils, viscosity index improvers, zinc-based anti-wear additives, oxidation inhibitors, corrosion protection additives, and anti-foam technology. The high viscosity index formulation maintains oil viscosity across changing temperatures, ensuring fast response during cold starts while maintaining a strong lubricating film at elevated operating temperatures.
