Royco 770

ROYCO 770

GENERAL INFORMATION:
ROYCO 770 is a super clean 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 designated as a P-15 protectant according to the Mil-STD-2073-1D standard.

APPLICATIONS:
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. ROYCO 46 is also a suitable lubricant for precision gearboxes where a low starting torque in cold temperature is required and in applications where it is necessary to pump semi-fluid grease through extremely small orifices.

Mil-Spec:
MIL-PRF-46170 Type I

ADVANTAGES:
Excellent rust and corrosion inhibition
Outstanding antiwear properties to extend life

COMPATABILITY:
ROYCO 770 should not be used in aviation hydraulic systems without prior evaluation and should not be used in systems in contact with natural rubbers. Intermixing ROYCO 770 with petroleum base stocks will reduce fire resistant properties.
