| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to O-ring damage. | Apply a light, even pressure. Lubrication is key to preventing tears. |
| Installing a twisted O-ring, compromising the seal. | Verify the O-ring is laid flat and evenly within the groove before assembly. |
| Using incompatible lubricants that degrade the Buna-N material. | Consult chemical compatibility charts to select a lubricant suitable for Buna-N and the operating environment. |
