| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening the assembly, which can crush the O-ring. | Tighten fasteners to the manufacturer's specified torque values. |
| Using an O-ring that is not compatible with the fluid or temperature. | Always verify material compatibility and operating temperature range before selecting an O-ring. |
| Damaging the O-ring during installation due to sharp edges. | Smooth any sharp edges on mating surfaces or use a protective sleeve during installation. |
