Why choose Zircon Z 68
Duckhams Zircon Z Hydraulic Oils are a range of anti-wear hydraulic oils blended using high-quality virgin base oils with a balanced additive system, which includes anti-wear and oxidation inhibitors. It is suitable for most types of mobile or stationary hydraulic systems, including gear-, piston- or vane pump hydraulic systems, operating over a wide range of ambient temperatures. Developed using high-quality virgin base oils these products meet or exceed industry standards for HM hydraulic fluids.
- High viscosity index makes these products suitable for use over a wide range of ambient temperatures.
- Excellent anti-wear performance protects components within hydraulic systems and reduces operating costs by extending pump life and minimising downtime.
- Excellent hydrolytic stability improves the protection of yellow metal components, even in the presence of water, extending component life.
- Good thermal and oxidative stability extends oil life reducing operating costs.
- Good sludge and particulate control maintains system cleanliness extending filter life and reducing filter change frequency.
- Excellent filterability.
- Good anti-rust and anti-corrosion properties protect the system.
- Compatible with elastomers commonly used as seals within hydraulic systems.
- Excellent water separation, air release and antifoam properties.
