QUESTIONS & ANSWERS
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.
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.
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.
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.
While Royco 756 hydraulic fluid is relatively low in toxicity, it is important to use standard personal protective equipment (PPE) such as gloves and safety glasses. Avoid prolonged skin contact and always consult the Safety Data Sheet (SDS) for detailed handling, storage, and disposal guidelines.
Yes! Royco 756 is suitable for both helicopters and fixed-wing aircraft. Its performance characteristics and wide operating temperature range make it versatile enough for rotorcraft hydraulic systems, especially where MIL-PRF-5606 compliance is required.
Royco 756 is compatible with common aviation seals, including nitrile (Buna-N), fluorosilicone, and Viton materials. It’s essential to confirm compatibility with OEM specifications before use, especially if seals have previously been exposed to synthetic fluids.
