Castrol Dual Range HV Hydraulic Fluids are exceptional multi-viscosity hydraulic fluids that provide proven anti-wear protection coupled with very shear stable polymers and anti-foam additives for a balanced package. An extreme load carrying capability is indicated where Castrol Dual Range HV Hydraulic Fluids pass the FZG Load carrying test at Stage 12. This outstanding performance provides the extra measure of protection required in high load applications such as hydrostatic transmissions and high speed/high pressure hydraulic circuits. Castrol Dual Range HV Hydraulic Fluids’ high viscosity indexes and their low pour points ensure extra pump protection and efficiency in cold weather starts and provide needed viscosity protection at higher operating temperatures. The products are dyed purple to facilitate leak detection.
