| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using a lubricant incompatible with Buna-N or the system fluid. | Consult chemical compatibility charts and select a lubricant specifically approved for Buna-N and the operating environment. |
| Forcing the O-ring into a tight groove, leading to nicks or tears. | Ensure the O-ring is properly sized for the groove and install with smooth, even pressure. Consider a specialized installation tool for very tight tolerances. |
