| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during installation, leading to compression set and premature failure. | Install with appropriate torque specifications, avoiding excessive compression which can permanently deform the O-ring. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Consult material compatibility charts and use only approved lubricants and cleaning solutions for Buna-N. |
