Frequently Asked Questions About Ceramic Fiber Gaskets
What are ceramic fiber gaskets made of?
Ceramic fiber gaskets are manufactured from high-purity alumina-silica ceramic fibers derived from melting and spinning natural minerals. They may include organic or inorganic binders for enhanced cohesion and flexibility, and can be reinforced with metallic wire or other materials for improved mechanical strength.
What is the maximum temperature for ceramic fiber gaskets?
Standard ceramic fiber gaskets withstand continuous temperatures up to 1260°C (2300°F). Specialty grades can handle up to 1427°C (2600°F) for short-term or intermittent exposure. Selection depends on your specific application requirements.
Are ceramic fiber gaskets safe and compliant with regulations?
Yes, our ceramic fiber gaskets are 100% asbestos-free and comply with OSHA, REACH, and RoHS regulations. We recommend using personal protective equipment (gloves, masks, safety glasses) during handling and installation to avoid respiratory irritation.
Can I buy ceramic fiber gaskets directly from a China manufacturer?
Absolutely. Kaxite Sealing is a direct China ceramic fiber gasket supplier offering factory prices with no intermediaries. Simply send us your requirements (temperature, pressure, size, quantity) and we will provide a competitive quote within 24 hours.
How do I choose the right ceramic fiber gasket for my application?
Key selection factors include maximum operating temperature, pressure, chemical exposure, flange size, and installation space. Review our specifications table and consult our technical team for personalized recommendations based on your application conditions.
What customizations are available for ceramic fiber gaskets?
We offer custom thicknesses (0.8–50.8 mm), densities (96–320 kg/m³), shapes, and sizes. Reinforcements with metal mesh or wire are also available. We can produce gaskets to your exact drawings or specifications. Contact our China sales team to discuss your custom requirements.
How long do ceramic fiber gaskets typically last in service?
Under normal operating conditions with continuous temperatures below 1093°C (2000°F), ceramic fiber gaskets can last several years. Regular inspection for compression loss, fiber degradation, or thermal aging is recommended to ensure optimal performance and timely replacement.

Ceramic Fiber Gasket
ceramic fiber gaskets are soft, lightweight and resilient, and have superior thermal characteristics. They are the perfect choice where an inexpensive heat seal with low sealing pressure is required. Since they are soft and can be easily laminated to form thicker seals, the flange finish is not particularly important when using this material
