Royco Aircraft Hydraulic Fluids

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 outstanding low-temperature fluidity as well as exceptional anti-wear, 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 is designed for use in aircraft, missiles, autopilots, and shock absorbers requiring all-weather performance. It 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°C to 90°C (-65°F to 195°F) and in pressurized systems from -54°C to 135°C (-65°F to 275°F) at pressures up to 3,000 psi.

This MIL-PRF-5606 hydraulic fluid comes in a 5-gallon container. (Other fluid sizes are available.)
