Extending the life of valve packing involves proactive maintenance and operational practices. Here are some strategies to consider:

1. **Proper Installation**: Ensure that packing is installed correctly, following manufacturer guidelines. Improper installation can lead to premature wear and leakage.

2. **Selection of Materials**: Choose the right packing material for the specific application, considering factors such as temperature, pressure, and the fluid being handled. This can greatly affect the lifespan of the packing.

3. **Regular Maintenance**: Schedule regular inspections and maintenance to identify wear and adjust packing as needed. This includes tightening gland nuts periodically to minimize leakage without over-compressing the packing.

4. **Lubrication**: Use appropriate lubricants to reduce friction between the packing and the valve stem. This can help in reducing wear and enhance the packing's life.

5. **Temperature and Pressure Control**: Operate valves within the designed temperature and pressure limits to avoid stressing the packing material.

6. **Minimize Vibration**: Prevent excessive vibrations in the system, as this can cause wear on the packing. Evaluate and adjust the system design if necessary.

7. **Avoid Over-Packing**: Over-packing can increase friction and lead to quicker degradation of the packing material. Ensure packing is appropriately adjusted.

8. **Monitor Performance**: Keep an eye on leaks and valve performance. Early detection of changes can help in timely interventions, preventing more significant issues.

9. **Use Spring-loaded Packing Glands**: These can help maintain a constant force on the packing, reducing wear over time.

10. **Consider Alternatives**: If leakage is a persistent issue, consider alternative sealing methods, such as mechanical seals, which might provide better longevity in certain applications.

By implementing these strategies, you can significantly extend the life of valve packing and reduce the frequency of maintenance and replacement.
