| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during assembly | Apply only the required torque to achieve a seal; overtightening can damage the O-ring and groove. |
| Using incorrect lubricant | Always use a lubricant compatible with both the O-ring material (Buna-N) and the system fluid to prevent degradation. |
| Installing on a damaged surface | Inspect the groove for sharp edges, scratches, or debris that could cut or nick the O-ring during installation. |
