    Information

    Royco 1MS (1.75-LB-TIN) is a specialized blend designed for precision lubrication in the aircraft industry. This compound combines lubrication grade micro fine powdered molybdenum disulfide meeting Mil-M-7866 standards with technical grade petrolatum conforming to VV-P-236. Notably, Royco 1MS is non-abrasive, offering exceptional shear stability and exhibiting lower volatility compared to alternative thread compounds.

    Key Features:

    • Electrical Conductor: Ideal for applications where electrical conductivity is required.
    • Excellent Shear Stability: Maintains consistent performance under varying pressures and temperatures.
    • Superior Anti-Seize Ability: Prevents seizing of threaded fasteners and fittings, enhancing maintenance efficiency.
    • Low Volatility: Minimizes evaporation, ensuring long-lasting lubrication performance.

    Applications:

    Royco 1MS is particularly suited for use on aircraft engine spark plugs and threaded fasteners and fittings operating below 800°F. Its electrical conductivity makes it ideal for anti-seize applications where the compound must not inhibit electrical current flow. For higher temperature applications, Mil-T-5544 compliant compounds such as ROYCO 44 are recommended.

    Enhance aircraft maintenance efficiency and reliability with Royco 1MS.
