MIL-PRF-32033

What is MIL-PRF-32033?

MIL-PRF-32033 is a United States military performance specification that defines the requirements for a specialised water-displacing, preservative lubricating oil for general-purpose applications at low temperatures.

This oil (formerly VV-L-800C) is typically a highly refined mineral oil blended with additives to provide superior rust and corrosion inhibition, especially after exposure to moisture. Its unique capability is the ability to rapidly displace water from metal surfaces, leaving behind a protective and lubricating film.

The oil is intended for both lubrication and protection against corrosion, with primary applications including:

  • Small Arms and Automatic Weapons: Lubrication and short-term preservation of weapons, including fuse mechanisms.
  • Water Displacement: Used after cleaning operations or exposure to water to prevent rust, mottling, or stains.
  • General-Purpose Lubrication: Recommended for locks, hinges, chains, electric motors, and general mechanical components.

Key Characteristics of MIL-PRF-32033

The MIL-PRF-32033 specification covers a single type and grade of oil, categorized by its distinct dual function and low-temperature performance.
