Flexible Graphite Packing

Flexible graphite packing braided from expanded graphite yarns, offering excellent heat resistance, chemical stability, .....


Flexible Graphite Packing is braided from high-purity expanded graphite yarns, forming a dense and resilient sealing material with excellent thermal stability and chemical resistance. Its self-lubricating nature and high conformability allow it to adapt closely to sealing surfaces, ensuring tight and reliable sealing performance even under demanding operating conditions.

This packing is widely used in high-temperature, high-pressure, and chemically aggressive environments, particularly in steam valve systems of power plants and static sealing positions where conventional packings are insufficient. It is compatible with most media except concentrated sulfuric acid and strong oxidizing agents.
