Your fluid choice can impact the performance of your aviation hydraulic system. That’s why you need a fluid developed to meet the requirements established by manufacturers and backed by recognized experts in phosphate ester technology. Skydrol was the first fire-resistant hydraulic fluid in the industry. Today, it remains the most advanced aviation hydraulic fluid. With Skydrol, you not only get a proven product but also access to our technical experts and unique sample analysis program.
Skydrol PE-5
Skydrol PE-5 is the first name in aviation hydraulic fluids. A Type V, fire-resistant hydraulic fluid specifically formulated to meet the changing needs of the aviation industry, PE-5 offers the longest fluid life of any phosphate ester fluid available today, even under high moisture conditions. With PE-5, you can experience less frequent fluid replacement, reducing disposal volume and decreasing your environmental footprint.
