YOKOHAMA
HYDRO S 22/32/37/46/68
Product Description
YOKOHAMA HYDRO S is a high-viscosity-index hydraulic oil range designed to support lubrication and wear control across a wide range of operating temperatures. Its viscosity-temperature characteristics help maintain fluidity during cold starts and a protective lubricating film under normal operating conditions. Oxidation stability, rust and corrosion control, water separation, filterability, air release and foam resistance support reliable operation of hydraulic pumps and control elements.
Application Areas
Intended for fixed and mobile hydraulic power systems requiring HV/HVLP-type fluids, particularly where ambient or operating temperatures vary. Suitable applications include construction and agricultural machinery, cranes, outdoor power units, presses, plastic injection moulding equipment and selected marine hydraulic circuits. The appropriate grade depends on pump design, service pressure and thermal conditions. Applications specifying fire-resistant or biodegradable fluids require separate products.
