| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, causing O-ring extrusion. | Adhere to specified torque values for all fasteners to prevent over-compression and extrusion. |
| Using incompatible lubricants that degrade the Buna-N material. | Always consult material compatibility charts for lubricants suitable for Buna-N and the operating environment. |
