ROYCO 777
ROYCO 777 is a synthetic fire resistant low
temperature hydraulic fluid.
ROCYO 777 is used for aerospace
applications
Royco 777 GENERAL INFORMATION: Royco 777
meets Mil Spec: MIL-PRF-87257
ROYCO 777 is a red colored synthetic hydrocarbon and ester based fluid.
Royco 777 is for use in
hydraulic systems which require reliable operation in both extreme low and
high temperature environs and all weather – all season performance outside the capability of traditional
Mil-H-5606, and
Mil-PRF-83282 fluids.
The high flash and fire points of Royco 777 also afford an improved margin of safety
over mineral based fluids. ROYCO 777 is formulated with state of the art
additive technology to provide superior oxidation and corrosion
resistance, antiwear, and antifoaming protection. ROYCO 777 is super clean
filtered to ensure optimum performance in particulate- monitored systems. Royco 777 TYPICAL PROPERTIES:

Royco 777 APPLICATIONS:
ROYCO 777 is recommended for use in aircraft, ordnance, and missile
systems operating from -54oC to +135oC. Royco 777 should be considered
for use in auto pilots, shock absorbers, brakes, flight-control systems,
hydraulic servo-control systems, and other systems using synthetic
elastomer seals.
Royco 777 is especially recommended for use in high
altitude aircraft that normally operate with extended loiter times and
high endurance levels such as UAV's and ELINT systems.
ADVANTAGES:
• Wide operating temperature range
• Low temperature fluidity.
• Improved safety with high flash and fire points.
APPROVALS:
ROYCO 777 meets all requirements and is qualified to MIL-SPEC:
MIL-PRF-87257A
