Flexible pure graphite yarn gland packing

 Pure Graphite Gland Packing Data Sheet 

The pure graphite packing, also referred to as graphite yarn gland packing or flexible graphite packing, is produced from premium-grade graphite filaments that provide excellent heat resistance, low friction, and outstanding dimensional stability. The material maintains its elasticity under constant thermal and mechanical loads, ensuring a long-lasting, leak-free seal in both static and dynamic systems. Engineered for superior performance, this pure graphite gland packing demonstrates exceptional chemical compatibility with steam, water, hydrocarbons, and most corrosive fluids. Its low wear characteristics protect shafts and sleeves, while the high thermal conductivity promotes efficient heat dissipation during high-speed rotation.

 Advantages 

1. 1. Suitable for high temperatures up to 650°C (non-oxidizing conditions)
2. 2. Excellent resistance to acids, alkalis, and organic solvents
3. 3. Low friction and self-lubricating performance
4. 4. Stable sealing properties under cycling pressures
5. 5. Easy to cut, install, and compress uniformly

 Typical Applications 

1. 1. Valves, turbines, and high-pressure pumps in power generation
2. 2. Petrochemical and refinery equipment
3. 3. High-temperature steam and condensate systems
4. 4. Mechanical seals in process industries

Each pure graphite packing is precisely braided to ensure uniform density and consistent sealing performance, delivering reliable service where conventional materials cannot endure.
