The ULTRA-HYD HLP Hydraulic Oil Series are suitable for most hydraulic systems where high levels of anti-wear and protection are required in conjunction with good service life reliability. They are also suitable for many other applications where machinery lubricants with excellent anti-wear lubrication and resistance to degradation in service are required. Applications can include systems incorporating high-speed gears and bearings, pumps, blowers and other uses where this type and quality of lubricant can assist with lubricant rationalisation.

The ULTRA-HYD HLP Hydraulic Oil Series is formulated using extremely high-quality base oils and incorporates additive treatments to provide excellent service life with protection against corrosion, wear, oxidation and foaming.
