The function of a hydraulic fluid is to transmit power by applying the fundamental principles of hydraulics as they relate to fluids in motion and to reproduce quickly, any change in direction or magnitude. Puroil Synthetic Hydraulic Oils are formulated from the highest quality synthetic base stocks exhibiting unmatched performance, low temperature stability and environmental compatibility. These hydraulics significantly reduce oil maintenance and afford a higher margin of safety to the environment should a line rupture or an accidental spill occur. The anti-wear performance of the Puroil Synthetic Series is easily 75% greater than any mineral or vegetable based hydraulic oil.

Puroil Synthetic Hydraulic Oils meet the EPA and US Coast Guard requirements for biodegradability set forth in 40 CFR 796.3260 and the acute aquatic toxicity (LC-50) criteria adopted by the EPA and US Fish and Wildlife Service.

Puroil Synthetic Hydraulic Oils with manufacturer prescribed viscosity exceed the requirements for industrial and mobile hydraulic systems which call for the following:

Vickers	35VQ25
Denison	HF-0
Cincinnati Milacron	P-68, P-69, P-70
