Description

Solar Hydraulic Oil ISO AW 680 is a top-quality, heavy-duty anti-wear hydraulic and circulating oil, formulated from premium-grade refined mineral base oils and advanced additive technology. Specifically designed for extremely high-load, slow-moving industrial equipment, this oil offers excellent film strength, outstanding wear protection, and superior resistance to oxidation and thermal stress. ISO VG 680 is ideal for systems operating under severe working conditions where extra heavy viscosity and reliability are essential.

Available API

Applications

Heavy industrial hydraulic systems working under extreme pressure and slow speeds.
Circulating oil systems for gears, bearings, and chains requiring ISO VG 680 grade fluids.
Steel mills, mining equipment, marine deck machinery, and heavy-duty press systems.
Systems requiring high-viscosity fluids for reliable lubrication under severe mechanical stress and high temperatures.

Key Features & Benefits:

Superior Anti-Wear Protection
Reduces component wear and extends service life in hydraulic systems, pumps, and gears operating under extreme loads.
Excellent Oxidation and Thermal Stability
Provides resistance to oil degradation at high temperatures, ensuring longer oil service intervals and reduced downtime.
Strong Rust & Corrosion Protection
Prevents metal surface corrosion and rust even in environments prone to moisture exposure.
Outstanding Air Release & Anti-Foaming Properties
Ensures smooth hydraulic system operation by preventing air entrapment and foam build-up.
Fast Demulsibility
Allows rapid separation of water from the oil, preventing emulsions and maintaining system efficiency.

Health & Safety:

Avoid prolonged skin contact. Use gloves during handling. In case of contact with skin or eyes, wash immediately with clean water. Dispose of used oil responsibly and consult the Material Safety Data Sheet (MSDS) for further information.
