| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Installing a damaged or defective O-ring. | Thoroughly inspect the O-ring for nicks, cuts, or deformation before installation. Always use new, undamaged seals. |
| Stretching or twisting the O-ring during installation. | Install the O-ring by working it into the groove evenly. If lubrication is used, apply it sparingly to prevent the O-ring from spinning or becoming distorted. |
| Using incompatible lubrication or cleaning agents. | Consult the O-ring material compatibility chart to ensure any lubricant or cleaning agent used will not degrade the Buna-N or the 316 stainless steel. |
