ROYCO 770 is a synthetic hydraulic fluid developed to meet the severe duty demands of today's military and industrial equipment. Rust inhibitors are utilized to provide protection to ferrous components and modern additive technology is employed for oxidative stability, corrosion inhibition, and antiwear protection. ROYCO 770 is intended for use in severe duty applications requiring extremes in environment and/or extended time periods between operation such as tank and howitzer recoil mechanisms and hydraulic systems, snow removal, earth moving and heavy duty construction equipment, and industrial robotic hydraulic systems. ROYCO 770 is especially recommended in applications where rust protection together with a high flash point can afford an extra margin of safety and fire protection.
