| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Installing a damaged or distorted O-ring. | Always visually inspect the O-ring for nicks, cuts, or deformation before installation. Replace if any damage is present. |
| Overstretching or twisting the O-ring during installation. | Install the O-ring using a smooth, rolling motion into the groove. Avoid pulling or forcing, which can cause permanent damage and lead to premature failure. |
| Installing into a contaminated or damaged groove. | Thoroughly clean the groove and ensure it is free of debris, sharp edges, or imperfections before inserting the O-ring. |
