MIL-PRF-680

MIL-PRF-680 is a military specification for degreasing solvents established by the United States Department of Defense, which consists of four types of petroleum distillates. The different types are referred to as "Stoddard solvent" (Type I), "141°F solvent” (Type II), "200°F solvent" (Type III), and "141°F d-limonene blended solvent" (Type IV). They are used for degreasing of machine parts in equipment maintenance.

MIL-PRF-680C Specification Overview

MIL-PRF-680C defines performance requirements for degreasing solvents used in military, aerospace, and defence maintenance environments. The specification focuses on solvent properties such as low odour, controlled evaporation, minimal non-volatile residue, and appropriate flash point levels to support safer cleaning and degreasing of parts, equipment, and components.

For buyers, this specification helps identify solvent products suitable for compliant cleaning tasks across aircraft maintenance, ground support equipment, weapons systems, and other MRO applications. Always review the product details and documentation for each solvent to confirm suitability for your specific cleaning requirement.

MIL-PRF-680: Frequently Asked Questions About Military Degreasing Solvents

What is the MIL-PRF-680 specification?

MIL-PRF-680 is a military performance specification for petroleum distillate degreasing solvents used to clean oils, greases, lubricants, coolants, and other soils from parts and equipment. It is commonly referenced for aerospace, defence, and military maintenance applications where compliant cleaning products are required.

What is the difference between P-D-680 and MIL-PRF-680?

P-D-680 was an earlier federal specification for dry cleaning and degreasing solvents used in military maintenance operations. MIL-PRF-680 replaced P-D-680 and provides updated performance requirements for degreasing solvents used in aerospace, military, and defence cleaning applications.

What is MIL-PRF-680C Type II degreasing solvent?

MIL-PRF-680C Type II degreasing solvent is commonly used for precision cleaning and degreasing in aerospace, military, and industrial maintenance environments. Type II products are often selected when a low-odour solvent with a higher flash point and low residue characteristics is required. Review the listed product details and documentation to confirm suitability for your specific cleaning application.

Where is MIL-PRF-680 commonly used?

MIL-PRF-680 degreasing solvents are commonly used in the maintenance of weapons systems, aircraft, ground vehicles, support equipment, and other military or aerospace components. These solvents help remove contaminants that can affect reliability, safety, and performance during MRO operations.
