WHAT ARE NON ASBESTOS GASKETS?
Non Asbestos Gaskets are advanced industrial sealing materials developed to replace traditional asbestos-based gaskets while maintaining excellent sealing performance and improved environmental safety. These gaskets are manufactured from a combination of synthetic fibers, aramid fibers, carbon fibers, inorganic fibers, elastomer binders, and optional metallic reinforcement.
Non Asbestos Gaskets provide reliable sealing under temperature fluctuations, pressure loading, and chemical exposure, making them widely used in modern industrial systems. They are considered an industry-standard solution for applications requiring both performance and compliance with current environmental requirements.
