| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade the Buna-N. | Always use lubricants specifically recommended for Buna-N and the application's operating conditions. |
| Over-stretching the O-ring during installation, leading to premature failure. | Install the O-ring with minimal stretch, allowing it to seat naturally in the groove. |
