High temperature valve packing

CARBOSTEAM is made of flexible carbon yarns and a special graphite-based impregnation. Thanks to its excellent thermal stability CARBOSTEAM is widely used in high temperature steam applications. Because of its high pressure and extrusion resistance CARBOSTEAM is ideally used as end rings for GRAFIFLEX and G-SPEZIAL  and.



  • Thermally stable carbon yarn and impregnation
  • Very high temperature resistance
  • High graphite content in impregnation
  • Reduced friction, longer service life
  • High strength carbon yarns
  • Used as anti-extrusion and wiper end rings with GRAFIFLEX or          G-SPEZIAL


Hot water, hot air, stem, acids and alkalis.

Exceptions :strongly oxidizing media such as hot sulfuric acid and nitric acid.
