| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-stretching the O-ring during installation. | Handle the O-ring with care and avoid excessive pulling. If resistance is met, re-evaluate the groove dimensions or the O-ring size. |
| Installing into a dirty or damaged groove. | Thoroughly inspect and clean the sealing groove before installation. Any nicks or burrs can compromise the seal integrity. |
