ZER0LEAK Expanded Graphited Gland Packing is engineered to deliver premium sealing performance in the most extreme industrial environments. Manufactured from high-purity expanded graphite yarn, this packing is known for its superior sealing characteristics, outstanding thermal stability, and chemical resistance—making it an essential choice for heavy-duty equipment used in aggressive media and high-pressure systems. Capable of handling temperatures from –240°C to +600°C, the packing material retains its shape and sealing power even in high-heat systems such as steam lines, heat exchangers, and thermal oil loops. It resists shrinkage and breakdown under thermal cycling and can also be used in cryogenic setups—offering unmatched thermal range flexibility. The graphite composition offers excellent self-lubricating properties, minimizing friction between the seal and shaft or valve stem. This not only reduces wear and energy consumption but also extends the lifespan of the equipment—ideal for reducing unscheduled downtimes and operational costs. The material also accommodates shaft movement without degrading or losing sealing integrity. ZER0LEAK Expanded Graphited Gland Packing is highly chemical-resistant, making it perfect for use with a wide range of aggressive fluids including acids, alkalis, hydrocarbons, and solvents. It is widely used in chemical processing plants, power stations, refineries, paper mills, food processing, and water treatment facilities. Installation is easy—cut the material to length and pack it into the stuffing box, valve, or groove. It conforms well to the sealing surface and compresses tightly to ensure zero leakage even in high-vibration or pressure-variable conditions. The packing is compressible and adjustable to different shaft diameters, allowing maximum sealing surface contact.
