| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-stretching the O-ring during installation, leading to premature failure. | Apply gentle, even tension during installation. If significant stretching is required, consider a larger O-ring size or alternative sealing solution. |
| Installing on contaminated or damaged sealing surfaces. | Thoroughly inspect and clean all mating surfaces to prevent leaks and O-ring damage. |
