| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Overtightening fasteners, compressing the O-ring beyond its elastic limit. | Tighten fasteners to the manufacturer's recommended torque specifications to avoid over-compression and premature failure. |
| Using incompatible lubricants or cleaning agents that degrade the Buna-N material. | Always consult material compatibility charts and use only lubricants and cleaning agents approved for Buna-N and the specific application environment. |
| Allowing the O-ring to twist during installation, creating a path for leakage. | Ensure the O-ring is seated squarely in the groove and does not twist during assembly. Gentle rotation might be needed to seat it properly. |
