Question:
What is Royco 756 aircraft hydraulic fluid used for?
Answer:

Royco 756 is a mineral-based hydraulic fluid primarily used in aviation systems that require compliance with the MIL-PRF-5606H specification. It is designed for use in aircraft hydraulic systems, shock struts, brake systems, and other components requiring a fire-resistant, low-viscosity fluid. It is widely used in both military and civilian aircraft operations.

Asked February 13, 2024
Question:
Can Royco 756 hydraulic fluid be used in brake and landing gear systems?
Answer:

Yes! Royco 756 is commonly used in aircraft brake systems and landing gear shock struts. Its excellent lubricity, thermal stability, and oxidation resistance make it suitable for high-load, high-stress aircraft components. It performs well across a broad temperature range, ensuring reliable operation in braking and strut systems.

Asked January 27, 2026
Question:
Is Royco 756 compatible with other hydraulic fluids?
Answer:

Royco 756 is compatible with other mineral-based hydraulic fluids that meet the MIL-PRF-5606H specification. However, it should not be mixed with phosphate ester-based fluids like Skydrol, as this can lead to system contamination or component damage. Always flush and service systems before switching fluid types.

Asked January 27, 2026
Question:
What is the shelf life of Royco 756 hydraulic fluid?
Answer:

When stored properly in its original, unopened container, Royco 756 has a shelf life of up to 4 years (48 months). To maintain its quality and performance, the fluid should be kept in a cool, dry place away from direct sunlight and extreme temperatures. Always follow manufacturer storage guidelines and check the production or expiration date before use to ensure compliance with aviation maintenance standards.
