KLINGERSIL Hochdruckdichtung

KLINGER® top-graph 2000

Combines the advantages of fibre-reinforced gaskets and flexible graphite

KLINGER®top-graph 2000 combines the advantages of fibre-reinforced gaskets with the key features of flexible graphite.


Graphite and synthetic fibres bonded with NBR.

Areas of application

Thanks to its high degree of inherent stability this material offers reliability in handling. Due to the high load bearing capacity and the low embrittlement, KLINGER®top-graph 2000 is ideal for the use with steam and other demanding applications.

KLINGERSIL® C-4300 ist eine universelle Hochdruckdichtung.

Key features

  • Utilization of graphite as filler
  • High Level of load bearing capacity


  • Improved flexibility
  • Resists high surface pressure also at elevated temperatures
