| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during assembly, leading to O-ring extrusion or damage. | Tighten fasteners to the manufacturer's recommended torque specifications to avoid over-compression. |
| Using the wrong O-ring material for the specific fluid or operating temperature. | Verify the chemical compatibility and temperature range of Buna-N against the application's requirements before installation. |
