Braided from Carbon fiber and carbon reinforced expanded Graphite Yarn
Characteristics
- Universal plant wide use in static and rotating applications
- Wear and extrusion stability through carbon fiber corner reinforcement
- Non hardening, good reset capability, coefficient of thermal expansion corresponds to the coefficient of steel
- High temperature resistance and excellent heat and electric conductivity
- Self lubricating, excellent use in pumps, minimizing the need of flushwater
- Easy to cut, assemble and disassemble
- Low coefficient of friction minimizes the adjustment force in valves
- No shaft wear, excellent dry running characteristics
- Rings should be compressed in valve applications at assembly approx. 15 - 20 % in height
- Die formed rings are recommended
