CNAF Gaskets
At Metrade, we provide reliable and cost-effective CNAF gaskets (Compressed Non-Asbestos Fiber Gasket) engineered for a wide range of industrial piping and flow control applications. Designed as a safe alternative to traditional asbestos materials, these gaskets deliver excellent chemical resistance, thermal stability, and durable performance without health risks.
Our CNAF gasket serve industries such as oil & gas, water treatment, chemical processing, power generation, and general manufacturing. They offer exceptional sealing properties, ensuring leak-free operation even in high-pressure, high-temperature, and chemically aggressive environments. Built for versatility and long-term reliability, Metrade’s gaskets help maintain system efficiency, reduce maintenance costs, and provide consistent protection for critical pipelines.

A CNAF gasket (Compressed Non-Asbestos Fiber gasket) is a widely used type of flat gasket made from a blend of aramid fibers, mineral fillers, and rubber binders, compressed under high pressure to form a durable, non-asbestos sealing material. Designed as a safer and more environmentally friendly alternative to traditional asbestos gaskets, CNAF gaskets offer excellent resistance to heat, pressure, water, oils, fuels, and many mild chemicals. They are commonly used in industries such as petrochemical, oil and gas, water treatment, and general industrial maintenance, particularly in flange joints, pumps, and valve connections. Their balance of sealing performance, chemical resistance, and affordability makes CNAF gaskets a popular choice for a wide range of sealing applications in non-extreme environments.
