| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible lubricants that degrade Buna-N. | Always consult compatibility charts for lubricants suitable for Buna-N and the specific application fluid. |
| Over-stretching or twisting the O-ring during installation. | Install the O-ring with minimal tension, ensuring it seats evenly within the groove to prevent premature failure. |
