| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using an O-ring with incorrect dimensions for the groove, leading to leaks or premature failure. | Always verify the O-ring's inside diameter, outside diameter, and cross-section precisely match the groove specifications. |
| Overtwisting or overstretching the O-ring during installation, causing damage and compromising seal integrity. | Install the O-ring without excessive stretching or twisting, ensuring it sits evenly within the groove. |
| Installing the O-ring into a contaminated groove, which can lead to abrasion and sealing issues. | Thoroughly clean the groove and all mating surfaces before O-ring installation. |
