| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Over-stretching O-ring during installation. | Gently ease the O-ring into the groove, using a blunt tool if needed, to prevent permanent deformation. |
| Using incompatible lubricant. | Consult material compatibility charts to select a lubricant that will not degrade the Buna-N elastomer or the stainless steel. |
