Royco 756 (1 x 946ml)

ROYCO 756 is a red-dyed, mineral oil-based hydraulic fluid developed for demanding aerospace and industrial hydraulic applications. It provides excellent low-temperature fluidity, anti-wear protection, oxidation and corrosion resistance, and good shear stability.

The high-viscosity-index formulation also contains metal deactivators and foam inhibitors to support reliable performance across a wide range of operating conditions.

Overview

ROYCO 756 is designed as a high-performance, general-purpose hydraulic fluid for aircraft and industrial equipment. Its additive system provides low-temperature performance, anti-wear protection, oxidation and corrosion inhibition, and resistance to fluid breakdown.

The fluid is manufactured to a high level of cleanliness and is particularly suitable for hydraulic systems where clean fluid can help improve component life and reliability.
