Graphite reinforced PTFE packing

Graphite  PTFE packing

Universal packing for high speed / high temperature pumps

Graphite reinforced PTFE packing consists of graphite-filled lubricated PTFE yarn. The special braiding structure offers the benefits of low thermal expansion and excellent heat conduction. Due to its low friction characteristics UNIVAL can also withstand dry running up to a certain limit. In addition, its pliable and dense composition allows UNIVAL to seal effectively with a minimum of gland pressure.
The materials used are approved for use in food processing industries.
