Eco-Friendly Non-Asbestos Sealing Gaskets
Raj Metals is a leading supplier of high-grade Non-Asbestos Gaskets, providing a safe and alternative to traditional asbestos-based materials. Our gaskets are manufactured from a specialized blend of synthetic fibers (such as Aramid or Carbon), mineral fibers, and high-quality elastomers (NBR, EPDM, or SBR). These Compressed Non-Asbestos Fiber (CNAF) gaskets offer excellent thermal stability and chemical resistance, making them the standard choice for sealing water, steam, oil, and mild chemical pipelines. Engineered for durability and environmental compliance, they provide a reliable, leak-proof seal across a wide range of industrial temperatures and pressures.
