    Parker's motion and control technologies are being utilized by our customers in applications around the globe. Parker continues to advance hydraulic technology with our introduction of DuraClean™, an ultra-premium hydraulic fluid designed to offer exceptional protection of hydraulic system componentry. This multigrade hydraulic oil protects against wear, oxidation, rust, corrosion and varnish.

    DuraClean™ hydraulic fluid was developed with a totally unique 'Clean Technology.' This hydraulic fluid has a unique additive chemistry, designed to maximize oil life while providing optimum anti-wear protection for the components of today's advanced hydraulic systems. This fluid innovation prevents harmful deposits from settling on components, protecting hydraulic systems from damage, component replacement, compromised performance and unanticipated downtime. Parker DuraClean™ makes it possible for hydraulic systems to 'Start Clean and Stay Clean.'

    DuraClean™ proves its ability to 'Start Clean' first by being packaged and shipped with an ISO cleanliness level of at least 17/15/12. This helps to ensure excellent hydraulic performance from the beginning of operation, leading to a longer filter life, increased component reliability, and less sampling on the initial fill.

    DuraClean™ proves its ability to 'Stay Clean' because of its unique additive chemistry and ability to resist oil oxidation. The byproducts caused from oil oxidation lead to varnish. Varnish is becoming more prevalent in hydraulic systems today as the size of reservoirs/components is decreasing, while the pressures used are increasing. The initial evidence of varnish is discoloration of metal surfaces caused by a soft sticky material. This soft sticky material clings to metal surfaces, attracts wear debris, and actually prevents anti-wear additives in the oil from attaching to the metal. The material then transitions into a very firm lacquer, causing increased friction within the hydraulic system which negates any of the power savings gained from using a smaller system. Varnish causes a chain reaction within a hydraulic system resulting in inconsistent operation, increased wear on componentry, reduced efficiency, and extended system downtime. These issues are completely preventable by using Parker DuraClean™ , saving our customers both time and the costs associated with the issues of system wear.

    The durable formulation of DuraClean™ provides excellent protection of components even after the fluid has been used extensively. These varnish protection solutions provide proven performance and viscosity retention in a wide temperature range, setting Parker DuraClean™ apart from competitive fluids.
