| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, which can excessively compress the O-ring and lead to premature failure. | Tighten fasteners to the manufacturer's recommended torque specifications, ensuring even pressure distribution. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Always use lubricants and cleaning agents specifically approved for Buna-N and the service fluid. |
| Installing a twisted or kinked O-ring, compromising its sealing ability. | Ensure the O-ring is laid flat and untwisted in the groove before assembly. |
