Packing, also known as compression packing or gland packing, is a sealing material used in pumps, valves, and rotating equipment to prevent fluid leakage while allowing controlled movement. Made from braided fibers such as graphite, PTFE, aramid, or carbon, packing is highly resistant to heat, chemicals, and mechanical wear. It is commonly used in steam applications, chemical processing, and power plants, ensuring long-term durability and minimal maintenance.
