| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade Buna-N. | Always use a lubricant compatible with Buna-N, such as silicone grease or a petroleum-based lubricant approved for Nitrile. |
| Overstretching or twisting the O-ring during installation. | Handle the O-ring with care and ensure it sits evenly in the groove without excessive tension. |
