QUESTIONS & ANSWERS

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

Royco 756 is a mineral-based aircraft hydraulic fluid formulated to meet MIL-PRF-5606H requirements. It’s commonly used in aviation hydraulic applications such as flight control systems, shock struts, and brake systems, along with other components that require a low-viscosity, petroleum-based fluid. It’s widely used across both military and civilian aircraft maintenance operations.

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

Yes. Royco 756 is frequently used in aircraft brake systems and landing gear shock struts, where consistent hydraulic performance is critical. Its lubricity and stability help support reliable function in high-load components, while its broad operating temperature range makes it suitable for demanding service environments. Always confirm system requirements against OEM and spec guidance before servicing.

Asked January 6, 2026
Question:
Is Royco 756 compatible with other hydraulic fluids?
Answer:

Royco 756 can generally be used in conjunction with other mineral-based fluids that also meet MIL-PRF-5606H standards. It should not be mixed with phosphate ester fluids, such as Skydrol, as mixing fluid types can lead to contamination and potential component damage. If switching fluid types, follow proper flushing and servicing procedures to protect the hydraulic system.

Asked January 6, 2026
Question:
What is the shelf life of Royco 756 hydraulic fluid?
Answer:

When kept in its original, sealed container and stored correctly, Royco 756 typically has a shelf life of up to 48 months (4 years). Store it in a cool, dry location, away from direct sunlight, moisture, and temperature extremes, to preserve its performance. For compliance and maintenance record-keeping, always check the container labeling for date information and follow the manufacturer's storage guidance.

Asked January 6, 2026
Question:
What safety precautions should be taken when handling Royco 756?
Answer:

Standard fluid-handling precautions are recommended when working with Royco 756. Wear basic PPE, such as gloves and safety glasses, and avoid prolonged skin contact. Clean up spills promptly. For specific handling, storage, and disposal instructions, refer to the product’s Safety Data Sheet (SDS) for guidance.

Asked January 6, 2026
Question:
Can Royco 756 be used in helicopters as well as fixed-wing aircraft?
Answer:

Yes. Royco 756 is used in both rotorcraft and fixed-wing aircraft when systems call for a MIL-PRF-5606H mineral-based hydraulic fluid. Its viscosity characteristics and temperature performance make it suitable for a variety of aviation hydraulic applications. As always, confirm the aircraft and component requirements before use.

Asked January 6, 2026
Question:
What types of seals and elastomers are compatible with Royco 756?
Answer:

Royco 756 is typically compatible with common aviation sealing materials, including nitrile (Buna-N), fluorosilicone, and Viton. However, seal compatibility can depend on the specific aircraft system and whether components were previously exposed to other hydraulic fluid types. Verifying OEM material compatibility is the safest way to avoid leaks or seal degradation.
