What are MilSpec lubricants?

The US Department of Defense (DOD) has developed a series of technical specifications called Military Standard, MIL-STD and Military Specifications, MIL-SPEC.

Informally called MilSpecs, these quality documents are designed to achieve standardization and the highest quality for products procured for the Navy, Air Force, Army, and Marine Corps.

They cover everything from lubricants to almost every supply they buy. These specifications help establish interoperability of parts, systems, and supplies so that they meet all minimum requirements, are common among suppliers, reliable in the field, are compatible with the armed forces logistics systems, and generally ensure our warfighters always have the best possible equipment in the field.

Why buy Neolube Milspec?

Since Neolube is widely used in nuclear power plants including the Naval Nuclear Propulsion Program, the specifications for performance and purity are paramount. The product is authorized for use in submarines meeting the stringent requirements of the Nuclear Powered Submarine Atmosphere Control Manual (S9510-AB-ATM-010/(U)).

The performance as a dry lubricant has been proven in over 50 years of continuous use by the US Navy Submarine Force. The lubrication performance and consistency from package to package are remarkable. Its use in more industrial applications is becoming more and more widespread as companies recognize the ability of Neolube to prevent thread galling and its superior performance generally as an anti-seize lubricant for stainless steel and aluminum fasteners.

Why buy MilSpec MIL-L-24131C?

These standards and specifications from DOD are also used by many other non-defense government agencies, global technical organizations, and industries all over the world. When you buy “MilSpec” quality Neolube, you can be assured that you get the highest quality product that is exactly repeatable from package to package.
