Ceramic Fiber Packing
Kaxite Sealing's Ceramic Fiber Packing provides superior heat resistance and durability for industrial sealing, making it ideal for high-temperature environments. Its unique ceramic fibers offer enhanced insulation and long-lasting performance, solving leakage issues and boosting efficiency. Designed for engineers and maintenance teams in plants, it ensures reliable protection and peace of mind. Choose Kaxite Sealing for a smarter, more effective sealing solution.
Ceramic Fiber Packing – High-Temperature Sealing for Demanding Applications
Kaxite Sealing offers premium ceramic fiber packing engineered for extreme thermal environments. Manufactured from high-purity ceramic fiber yarns with advanced impregnation technologies, our packing delivers exceptional heat resistance, chemical stability, and mechanical resilience – ideal for sealing rotary and reciprocating pumps, valves, and static equipment in steel, power generation, petrochemical, and marine industries.
What sets Kaxite apart? Our in-house braiding lines enable precise control over packing density and impregnation uniformity – critical factors that directly impact sealing life and leakage control. Each batch is tested on our proprietary high-temperature compression rig, simulating real-world pump and valve conditions before shipment.
With four tailored variants – PTFE-impregnated, stainless steel wire reinforced, glass filament reinforced, and silicone rubber core – Kaxite ceramic fiber packing provides a versatile, cost-effective solution that reduces leakage, extends equipment life, and minimises maintenance downtime.

Frequently Asked Questions
- Q: What is the maximum temperature for ceramic fiber packing?
- A: Kaxite ceramic fiber packing can be used continuously from –100 °C up to +850 °C. Short-term excursions up to +1000 °C are permissible, but we recommend confirming with our engineers for your specific thermal cycling profile.
- Q: Which variant should I choose for a rotary pump application?
- A: For rotary pumps, we recommend Kaxite P803S (PTFE-impregnated) for general service, or Kaxite P803SS (stainless steel wire reinforced) for higher pressures or abrasive media. Our technical team can assist with material selection.
- Q: Is ceramic fiber packing suitable for steam applications?
- A: Yes. Ceramic fiber packing exhibits excellent resistance to steam and hot air. For high-pressure steam (above 15 bar), we recommend the SS-wire reinforced variant (P803SS) for added mechanical strength.
- Q: What sizes are available?
- A: Standard sizes range from 3 mm to 50 mm in square or round cross-section. Custom dimensions, pre-cut rings, and coils are available upon request.
- Q: Do you provide samples before bulk orders?
- A: Absolutely. We supply free material samples (shipping cost applies) for you to evaluate quality, flexibility, and heat resistance. Sample orders are processed within 3–5 working days.
- Q: What is the typical lead time?
- A: Standard sizes and grades: 7–15 working days. Custom dimensions or special impregnations: 15–25 working days, depending on quantity. Expedited production is available for urgent orders.
