CHEVRON HYDRAULIC OILS AW
ISO 32, 46, 68
PRODUCT DESCRIPTION
Chevron Hydraulic Oils AW are designed to give
excellent hydraulic pump protection.
CUSTOMER BENEFITS
Chevron Hydraulic Oils AW deliver value through:
• Good oxidation stability — Provide good service
life in high pressure service.
• Rust and corrosion protection — Give excellent
protection against corrosion of both copper and
steel, and passes the ASTM D665A distilled water
rust test and ASTM D665B synthetic sea water rust
test.
• Minimum viscosity change over a wide
temperature range.
• Good foam inhibition — Contain special foam
suppressant, minimizing both foaming and aeration
problems.
• Excellent antiwear properties
• Meets major pump manufacturer’s
requirements — ISO 32, 46, and 68 meet the
requirements of leading hydraulic pump
manufacturers for antiwear-type hydraulic fluids in
both vane- and piston-type pumps.
• Good stability in the presence of water by
ASTM D2619 Hydrolytic Stability test and the
Denison hybrid T6H20C Wet Pump test.
• Good thermal stability in the presence of copper
and steel by the MAG Cincinnati Machine Thermal
Stability, Procedure A, test.
• Fast water separation — Minimize rust problems
