1. Ensure the sealing groove is clean, dry, and free of debris. Inspect the groove for any damage or imperfections. 2. Carefully place the O-ring into the groove, ensuring it is seated evenly and not twisted. 3. Apply a thin layer of compatible lubricant to the O-ring and the mating surface before assembly to prevent damage during installation and operation.

| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using excessive force during installation, leading to O-ring damage or extrusion. | Handle the O-ring with care and use appropriate tools for installation. Avoid stretching or deforming the O-ring beyond its designed limits. |
| Installing into a dirty or damaged groove, compromising the seal integrity. | Thoroughly clean and inspect the sealing groove before installation. Address any nicks, burrs, or corrosion that could lead to leaks. |
