QUESTIONS & ANSWERS

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 MIL-PRF-5606H specification compliance. 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 July 17, 2025
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 July 17, 2025
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 July 17, 2025
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.

Asked July 17, 2025
Question:
What safety precautions should be taken when handling Royco 756?

Asked July 17, 2025
Question:
Can Royco 756 be used in helicopters as well as fixed-wing aircraft?
Answer:
