| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening during installation, leading to premature compression set and seal failure. | Apply only sufficient force to seat the O-ring. Consult application-specific torque specifications if applicable. |
| Using an O-ring with incompatible material for the specific fluid or operating temperature. | Verify the chemical and temperature compatibility of the Buna-N elastomer and 316 stainless steel with the intended application before selection. |
