| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to nicks or tears in the O-ring. | Apply lubrication compatible with Buna-N and gently guide the O-ring into place. Use a rounded tool if necessary, but avoid sharp edges. |
| Incorrect O-ring size, resulting in improper sealing or premature failure. | Always verify the O-ring's inside diameter, outside diameter, and cross-section against the specified groove dimensions before installation. |
