| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using the wrong O-ring material for the specific fluid or temperature application. | Always verify material compatibility with the operating environment, referencing chemical resistance charts for Buna-N and other available elastomers. |
| Over-tightening or excessive force during installation, leading to O-ring damage. | Install O-rings with minimal force, ensuring they seat properly without being cut, nicked, or stretched beyond their elastic limit. |
