MIL-PRF-83483

MIL-PRF-83483 is a military specification for a thread compound designed to prevent seizing, galling and corrosion on threaded fasteners. The specification outlines the testing procedures, manufacturing requirements, inspection methods, and performance criteria that manufacturers need to follow to meet the standard. Used in aircraft and aerospace applications, where high strength, flexibility, and corrosion resistance are critical. It can also be used in other industries requiring high-performance compounds. Composed of molybdenum disulfide and petrolatum. The most recent version of the spec is MIL-PRF-83483E, with several updates and amendments made previously. Common applications include military aircraft engine spark plugs, threaded fasteners and fittings.

MIL-PRF-83483 Key Features

  • MoS2 Based: The primary component is Molybdenum Disulfide, a solid lubricant known for its high-temperature performance and resistance to extreme pressures. It is also suspended in a petrolatum base, providing a protective coating and enhancing its adhesion properties

  • Temperature Range: Can withstand a high temperature range of up to 800°F (427°C).

  • Applications: Threaded fasteners, spark plugs, fittings, and other critical components in aerospace, aviation, and industrial applications.

  • Prevents Seizing: Reduces friction between threads, preventing them from becoming locked together.

  • Reduces Galling: Prevents metal-to-metal contact and the formation of wear.

  • Resists Corrosion: Parts are often exposed to harsh environments. They are required to be resistant to corrosion from moisture, chemicals, and other environmental factors.
