Graphite Packing GR8048A

Composition

Flexible expanded graphite strands braided together PAN carbon yarns 

Impreganted with graphite powder and inhibitor of corrosion

Characteristics

The GR8048A packing is the ideal solution to ensure maximum sealing of industrial valves and pumps, thanks to the combination of carbon fiber and expanded mineral graphite yarns. The special solution based on pure graphite powder and corrosion inhibitor applied to the packing minimizes fugitive emissions, increasing the sealing level. The GR8048A packing is highly elastic and reliable at high temperatures, and thanks to the graphite yarn with continuous PAN carbon fibers, it offers great resistance against extrusion and wear. Easy to install in the stuffing box, GR8048A packing is the ideal solution for multiple industrial applications.

Applications

The graphite packing GR8048A is equipped with a double yarn, making it particularly versatile and suitable for various industrial applications. Thanks to its high elasticity and reliability at high temperatures, it can be used in high-pressure and high-temperature static services, such as in sealing valves and pumps in chemical and energy processes. Moreover, thanks to its resistance to extrusion and wear, it can be successfully applied in dynamic services, such as those of soot blowers and diathermic oil systems. The graphite packing GR8048A can be used with all non-oxidizing fluids compatible with graphite, ensuring a high level of sealing and minimizing fugitive emissions. The graphite packing GR8048A represents the ideal solution for those seeking a versatile, reliable, and resistant product to use in various industrial applications, ensuring high performance in every operational context.
