| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect O-ring size for the groove. | Verify the groove dimensions against the O-ring's Inside Diameter, Outside Diameter, and Cross Section specifications for a proper fit. |
| Installing the O-ring with a dry surface. | Apply a small amount of compatible lubricant to ease installation and prevent material damage, ensuring the lubricant is compatible with the O-ring material and the fluid being sealed. |
| Using sharp objects to force installation. | Employ proper installation tools or techniques that avoid pinching, cutting, or otherwise damaging the O-ring during placement. |
