Carbon Fiber Packing
Product Description
Product Detail
Engineered Carbon Fiber Packing – High-Temperature Valve & Pump Sealing Solution
As an ISO 9001:2015 certified manufacturer with over 15 years of experience in braided packing production, we engineer our Carbon Fiber Packing (Style KXT P500) to deliver reliable, long-lasting sealing performance in demanding rotary and reciprocating applications. Unlike conventional packing materials, our carbon fiber packing combines exceptional thermal stability, chemical resistance, and self-lubricating properties to minimize valve stem wear and reduce maintenance downtime.
Manufacturing Excellence & Material Engineering
Our carbon fiber packing is braided from high-quality continuous carbon fiber yarns that undergo a proprietary softening and impregnation process. Each strand is thoroughly saturated with graphite particles and high-performance lubricants that fill microscopic voids, act as a break-in lubricant during initial operation, and form an effective barrier against fluid leakage. The result is a dense, flexible, and dimensionally stable packing that conforms perfectly to the stuffing box while maintaining low friction throughout its service life.
The KXT P500 carbon fiber packing is available in a wide range of cross-sections and spool sizes to accommodate standard and custom stuffing box dimensions. We produce both square and braided-over-core configurations, with options for pre-formed rings or continuous spool lengths for field installation.
✔ Field-Proven Performance:
Our carbon fiber packing has been successfully deployed in over 60 countries across chemical processing, power generation, pulp & paper, and steel industries. We back every product with full material traceability, batch-level COA (Certificate of Analysis), and mill test certificates.
Technical Authority & Compliance Standards
Our carbon fiber packing is manufactured in strict compliance with ASTM F1459 (Standard Specification for Braided Packing) and API 622 (Type 2 packing performance standards). Each production batch undergoes rigorous quality control, including density verification, lubricant content analysis, and dimensional accuracy inspection, ensuring consistent performance from spool to spool.

Key Advantages of Our Carbon Fiber Packing
- Exceptional temperature resistance: Withstands extreme temperatures from -150°C to +750°C, making it ideal for high-heat applications such as steam valves, furnace doors, and exhaust systems.
- Low coefficient of friction: The graphite-impregnated carbon fiber ensures minimal valve stem wear, extending equipment life and reducing costly downtime.
- Broad chemical compatibility: The pH range of 0–14 allows for use with acids, alkalis, solvents, alcohols, water (hot and cold), and heat transfer fluids.
- Cost-effective sealing solution: Compared to PTFE or metallic packings, our carbon fiber packing offers a high-performance alternative at a very competitive wholesale price.
- Easy installation: The braided construction offers excellent flexibility, allowing for quick and simple installation in standard and custom stuffing boxes.
