For over two decades, Kaxite Sealing has been at the forefront of sealing technology, engineering high-performance sealing solutions for the most demanding industrial applications. The global shift away from hazardous asbestos materials has made the selection of reliable, safe, and effective non-asbestos gaskets more critical than ever. Our comprehensive range of non-asbestos gasket materials is designed to meet and exceed the rigorous standards of modern industry, offering superior sealing integrity, enhanced safety, and long-term reliability without the health and environmental risks associated with traditional asbestos-based products.
Our non-asbestos gaskets are manufactured using advanced composite materials that provide exceptional resistance to heat, pressure, and chemical attack. Engineered for versatility, they are suitable for a wide array of services including steam, water, oil, gas, acids, and alkalis across various industries such as petrochemical, power generation, marine, and manufacturing.
Kaxite Sealing offers a tiered product line to match specific application requirements. Below is a breakdown of our primary non-asbestos gasket series.

What exactly are non-asbestos gaskets made from?
Non-asbestos gaskets are composite materials manufactured using safe, synthetic or inorganic fibers such as aramid (e.g., Kevlar), glass, carbon, or ceramic fibers. These fibers are bound together using various elastomers like nitrile rubber (NBR), styrene-butadiene rubber (SBR), or PTFE. This combination creates a sheet material that replicates or exceeds the sealing performance of historical asbestos-based gaskets without any of the associated health hazards.
Are Kaxite Sealing non-asbestos gaskets suitable for high-pressure steam applications?
Yes, absolutely. Our KAX-NA300 and KAX-NA500 series are specifically engineered for high-temperature and high-pressure services. The KAX-NA300 is excellent for standard high-pressure steam lines, while the KAX-NA500 is designed for superheated steam and extreme conditions. It is crucial to select the grade based on the specific temperature, pressure, and media of your application.
How do I select the right non-asbestos gasket material for my application?
Selection depends on four key factors: Temperature, Pressure, Media (chemical compatibility), and Flange Type/Surface. First, identify the continuous and peak operating temperatures. Second, know the system pressure. Third, and most importantly, verify the chemical resistance of the gasket material against the specific fluid or gas. Our technical datasheets provide detailed chemical resistance charts. Finally, consider the flange condition and bolting load. Our technical support team can assist with this analysis.
What is the shelf life of Kaxite non-asbestos gasket sheets?
When stored correctly in a cool, dry place away from direct sunlight, ozone, and extreme temperatures, our non-asbestos gasket materials have a shelf life of 5 to 7 years from the date of manufacture. The materials should be stored flat, not on their edge, to prevent deformation.
Can non-asbestos gaskets be used as a direct replacement for asbestos gaskets?
In the vast majority of applications, yes, they are designed as direct drop-in replacements. However, it is not always a simple 1:1 swap. Non-asbestos materials may have different thickness, compressibility, and torque requirements. It is recommended to consult replacement guides or our engineering team to ensure proper selection and installation procedures, which may involve adjusting bolt torque to achieve the optimal seal.
How do I ensure a proper seal when installing a non-asbestos gasket?
Proper installation is critical. Ensure flange faces are clean, undamaged, and aligned. Use a new gasket of the correct size and material grade. Follow a star-pattern bolting sequence and torque the bolts in multiple incremental passes to the recommended value specified by the gasket manufacturer or flange standards. This ensures even compression and distribution of the sealing stress across the entire gasket face.
Do you offer custom-cut gaskets or sheets only?
Kaxite Sealing provides maximum flexibility. We supply standard sheets and rolls for in-house fabrication. Additionally, we offer a full custom fabrication service where we can die-cut, CNC machine, or waterjet-cut gaskets to your exact specifications, including complex geometries and multi-layer designs. This ensures precision, reduces on-site waste, and saves valuable installation time.
