| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-stretching the O-ring during installation. | Gently ease the O-ring into the groove without excessive tension. A slight twist may be needed, but avoid significant stretching. |
| Using incompatible lubrication that degrades Buna-N. | Consult the O-ring material compatibility chart and use only lubricants specifically approved for Buna-N elastomers. |
