Why should grease guns be filled with a grease cartridge?

• A. Grease cartridges do not contain dirt contaminants
• B. Cartridges are cheaper
• C. Cartridges are easier to handle
• D. Grease cartridges prevent leaks

Answer: (A)

The main idea is keeping the lubricant clean. Grease needs to stay free from dirt and moisture to protect bearings and seals from wear and damage. When you use a grease cartridge, the grease is sealed in a clean, factory-packaged unit and loaded into the gun with minimal exposure to the environment. This packaging prevents dirt, dust, and moisture from getting into the grease before it’s applied, which is why cartridges are preferred. While there may be practical benefits like consistent grease grade and easier handling in some cases, the strongest reason is to avoid introducing contaminants into the lubrication path.
