Our carbon fiber packing is engineered for demanding sealing applications in valves and pumps across chemical, petrochemical, and power industries. This high pressure carbon fiber packing combines a carbon fiber core, PTFE corrosion barrier, and graphite lubricant to deliver reliable performance where conventional packing fails. Whether you need corrosion resistant carbon fiber packing for acid service or carbon fiber braided packing for high-speed rotating shafts, our product line offers a grade to match your operating conditions.
Applications of Carbon Fiber Packing – Critical Applications
| Application | Key Challenge | Our Solution |
| Chemical & Petrochemical Plants | Sulfuric acid, caustic soda, organic solvents | Carbon fiber core + PTFE barrier resists pH 0–14 |
| High-Pressure Valves & Pumps | Seal collapse at 40+ MPa | Dynamic compression recovery maintains sealing force |
| Offshore & Subsea Equipment | Saltwater corrosion, deep-sea pressures | Non-galling, salt-resistant grade available |
| Pharmaceutical & Food Processing | Zero contamination, FDA compliance | FDA-compliant PTFE grades for sanitary applications |

Frequently Asked Questions
Q: What is the maximum pressure rating for carbon fiber braided packing?
A: Our CF-400 grade is rated up to 60 MPa, while CF-200 is rated for 40 MPa. The actual pressure capacity depends on shaft speed, temperature, and media compatibility. Contact us with your operating conditions for a specific recommendation.
Q: Can this packing be used with sulfuric acid?
A: Yes. The PTFE corrosion barrier provides excellent resistance to concentrated sulfuric acid at temperatures up to 200°C. For higher concentrations or temperatures, we recommend the CF-400 grade or a custom formulation.
Q: Do you offer FDA-compliant grades for food processing?
A: Yes, our CF-FDA grade uses FDA-compliant PTFE and lubricants. It is suitable for sanitary pumps and valves in food and pharmaceutical applications.
Q: What is the difference between carbon fiber and graphite packing?
A: Carbon fiber packing has a fibrous structure that provides better mechanical strength and resilience under high pressure. Graphite packing is softer and more conformable but has lower tensile strength. Our carbon fiber packing includes a graphite lubricant layer to combine both benefits.
Q: How do I select the correct braided packing size for my pump shaft?
A: Measure the stuffing box depth and subtract the gland follower length. The packing cross-section should be slightly smaller than the gap between the shaft and the stuffing box wall. Our selection guide provides a detailed step-by-step process.
