In today's demanding industrial landscape, the quest for reliable, safe, and high-performance sealing materials is paramount. Non-asbestos gaskets have emerged as the definitive answer, completely replacing hazardous asbestos-based materials. Kaxite Sealing, a leader in advanced sealing technology, manufactures premium non-asbestos gaskets designed to meet and exceed the rigorous standards of various industries, including oil & gas, chemical processing, power generation, and marine applications. Our commitment is to provide sealing solutions that ensure operational safety, environmental compliance, and long-term cost-efficiency without compromising on performance.
Unlike traditional asbestos gaskets, our products are engineered using a sophisticated blend of high-quality aramid fibers, glass fibers, nitrile rubber (NBR), and other synthetic materials. This composition delivers exceptional resistance to heat, pressure, and a wide range of corrosive media, all while being completely safe for personnel and the environment. Choosing Kaxite Sealing means investing in durability, reliability, and peace of mind.
The superior performance of Kaxite Sealing non-asbestos gaskets stems from their advanced material formulation. Below is a detailed breakdown of the primary components and their inherent properties:

What exactly are non-asbestos gaskets?
Non-asbestos gaskets are sealing materials manufactured using modern, safe synthetic fibers and elastomers as a direct and superior replacement for traditional asbestos-based gaskets. They are designed to create a leak-tight seal between two mating flanges in piping and equipment, handling various pressures, temperatures, and chemical media without the health risks associated with asbestos.
Why should I choose non-asbestos gaskets over other types?
Choosing non-asbestos gaskets from Kaxite Sealing eliminates the serious health hazards of asbestos exposure (like asbestosis and mesothelioma) during installation, maintenance, and disposal. Furthermore, they offer comparable or often superior mechanical and thermal performance, better consistency in quality, and ensure compliance with global health, safety, and environmental regulations (like OSHA, REACH).
Are Kaxite Sealing non-asbestos gaskets suitable for high-temperature applications?
Absolutely. Our product line includes specialized grades like KAX-NA200 and KAX-NA400 engineered for high and extreme-temperature service. These grades utilize advanced aramid and glass fiber blends with high-temperature binders, capable of continuous operation at temperatures up to 400°C (750°F) and even 500°C (930°F) for specific grades, making them perfect for steam systems, exhausts, and thermal fluid applications.
How do I select the correct grade of non-asbestos gasket for my application?
Selection depends on four key parameters: the fluid or gas being sealed, its temperature, its pressure, and the flange type/surface finish. Always cross-reference the chemical compatibility of the gasket material with your process media. Use our temperature/pressure rating tables as a guide. For critical applications, consult with Kaxite Sealing's technical support team who can provide a detailed recommendation based on your specific operating conditions.
What is the proper installation procedure for these gaskets?
Correct installation is crucial for optimal performance. Ensure flange surfaces are clean, undamaged, and aligned. The gasket should be centered on the flange. Use a calibrated torque wrench and follow a star-pattern tightening sequence to apply the recommended bolt load evenly. Always refer to the equipment manufacturer's guidelines or Kaxite's technical datasheets for specific torque values, which depend on gasket type, size, and bolt class.
Can Kaxite non-asbestos gaskets be used as a direct replacement for old asbestos gaskets?
In the vast majority of cases, yes. They are designed as drop-in replacements. However, it is an excellent opportunity to review the application's current operating conditions. We recommend verifying the temperature and pressure ratings of our chosen grade against your system's actual requirements. Often, upgrading to a Kaxite non-asbestos gasket not only replaces the old material safely but can also improve seal longevity and reliability.
Do you provide custom shapes and sizes?
Yes, at Kaxite Sealing, we understand that standard sizes don't fit every need. We offer full custom manufacturing services. We can produce non-asbestos gasket sheets, cut gaskets in any shape (oval, rectangular, irregular), and supply full flange gasket sets with precise bolt holes. Simply provide us with a drawing, sample, or precise specifications, and our team will handle the rest.
How do Kaxite gaskets ensure environmental compliance?
Our non-asbestos gaskets are manufactured from environmentally conscious materials that are free from hazardous substances restricted by RoHS, REACH, and other global directives. Their production and end-of-life disposal do not pose the same severe environmental risks as asbestos. Using our products helps your facility maintain a safer workplace and meet its corporate sustainability and regulatory compliance goals.
