| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, crushing the O-ring and compromising the seal. | Adhere to specified torque values for all fasteners. Use a torque wrench for accurate tightening. |
| Using a lubricant incompatible with Buna-N or the specific application media. | Consult material compatibility charts and select a lubricant specifically recommended for Buna-N and the operational environment. |
