| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect lubricant that degrades Buna-N. | Always use lubricants specifically recommended for Buna-N seals to prevent premature failure. |
| Forcing the O-ring into the gland, causing damage. | Ensure the O-ring is the correct size for the gland and use gentle, even pressure during installation. Avoid sharp tools. |
