Royco 481, 55GAL/208,2L

ROYCO® 481 is a mineral oil-based lubricant formulated with modern additive technology to provide effective oxidation and corrosion protection together with a high viscosity index for excellent low- and high-temperature fluidity. Designed for aircraft turbine applications, it can be used for lubrication of gas turbine engine components and as a flushing and preservative fluid for aircraft fuel systems. ROYCO 481 is also approved as a P-10 preservative under MIL-STD-2073-1C.

Applications:

ROYCO 481 is recommended for the lubrication of gas turbine engine components and for use as a flushing and preservative fluid in aircraft fuel systems and their components. Its high viscosity index supports operation over a wide temperature range in high-speed turbines and gas turbine engines. The product may also be considered as the primary turbine engine lubricant in many aircraft turbine engines designed to operate with mineral oil-based lubricants.

Typical applications:

• Gas turbine engine components
• Aircraft turbine engines
• High-speed turbines
• Aircraft fuel systems and components
• Flushing of aircraft fuel systems
• Preservation of aircraft fuel systems
• Preservation of turbojet engines and engine parts
• Aircraft turbine engines designed for mineral oil-based lubricants

Product advantages and benefits:

• Excellent corrosion protection: provides outstanding rust and corrosion prevention for aircraft turbine engine components and fuel systems.
• Preservative properties: suitable for preservation of turbojet engines, engine parts and aircraft fuel systems.
• Oxidation protection: modern additive technology helps protect the lubricant against oxidation during operation and storage.
• High viscosity index: provides suitable fluidity over a wide range of low and high operating temperatures.
• Excellent low-temperature performance: a pour point of -62°C supports fluidity under very low-temperature conditions.
• High flash point: a flash point of 300°C provides excellent high-temperature characteristics.
• Ashless additive technology: formulated with ashless additives for demanding aviation lubrication and preservation applications.
• Versatile use: can serve as a lubricant, flushing fluid and preservative fluid in suitable aircraft turbine and fuel system applications.

Approvals and specifications:

• MIL-PRF-6081D Amendment 1, Grade 1010 – meets all requirements and is qualified
• MIL-PRF-6081D Amendment 1, Grade 1010N – meets all requirements and is qualified
• MIL-STD-2073-1C – approved as a P-10 preservative for use in gas turbine engines and fuel systems
