Graphite Packing
GRAPHITE PACKING
Graphite packing is braided from high-purity graphite filaments and graphite foils, and offers excellent chemical resistance, are thermally conductive, and can be used in extreme temperature and pressure conditions. Reinforced with high purity graphite fiber yarn, graphite packing is designed for leakage control, a long service life.
PROPERTIES
- Low abrasion and high chemical resistance for long service life
- Offset square design
- Contains passive corrosion inhibitor
- Low coefficient of friction
- Withstands elevated temperatures and aggressive chemicals
