| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong lubricant, which can degrade Buna-N. | Always use a lubricant recommended for Buna-N seals and the specific application fluid. |
| Overtightening fasteners, which can deform the O-ring and its groove. | Follow specified torque values for all assembly hardware to prevent over-compression. |
