ROYCO 756 AND ROYCO 756A
HYDRAULIC FLUID, AIRCRAFT, MISSILE, AND ORDNANCE PETROLEUM BASE
ROYCO 756 is a red-dyed, mineral oil based hydraulic fluid developed for
the severe duty demands of aerospace and industrial service. ROYCO 756
contains additives that provide excellent low temperature fluidity as
well as exceptional antiwear, oxidation - corrosion inhibition, and shear
stability. In addition, metal deactivators and foam inhibitors are
provided in this high viscosity index fluid to enhance performance in many
general purpose hydraulic applications.
ROYCO 756 meets all requirements and is qualified under MIL-SPEC:
Mil-PRF-5606H that supersedes Mil-H-5606,
Mil-O-5606, AN-O-336, AN-VV-O-336, and AAF-3580. ROYCO 756A meets
ROYCO 756 is designed for use in aircraft, missiles, autopilots, shock
absorbers, cherry pickers, boom trucks, robotics, and auto wreckers
requiring all - weather performance. ROYCO 756 is particularly recommended
for use in systems where a "super clean" fluid can contribute to improved
component life and reliability. ROYCO 756 can
be used in unpressurized systems operating at temperature ranges from -54
to 90°C (-65 to 195°F) and in pressurized systems from -54 to 135°C (-65
to 275°F) at pressures up to 3000 psi. ROYCO 756A may be used in
systems not requiring a “super clean” id and where the convenience of a
resealable container can provide cost savings.
