Non-Asbestos Gland Packings

Non-asbestos gland packings are advanced sealing materials that substitute the conventional asbestos-based packings. The packings consist of high-performance synthetic fibers, PTFE, graphite, or other modern materials. This offers superior sealing performance in industrial applications without the health and environmental risks associated with asbestos.
