Buying Guide
What should you consider when choosing grease for a grease gun? Start with the NLGI grade. For most automotive and light industrial tasks, NLGI #2 offers a good balance of firmness and pumpability. If you need maximum staying power in wet conditions, look for tackier formulas with water resistance. For high-temperature or extreme-pressure use, select greases designed for elevated temperatures and heavy loads.
- Temperature range and load: Match the grease’s range to the operating environment.
- Water exposure: Water-resistant and marine greases reduce washout.
- Compatibility: Ensure the grease is compatible with seals, metals, and your equipment.
- Gun compatibility: Verify cartridge size and gun compatibility to avoid pumping issues.
- Maintenance intervals: Heavier formulations may extend lubrication intervals but require more effort to apply.
