General service packing for high temperature steam valves

G-SPEZIAL is made from temperature – resistant flexible graphite yarns, reinforced with a thin Inconel wire. This highly pressure-resistant braided packing has the same excellent sealing effect as pure die-formed graphite rings. G-SPEZIAL is particularly suitable for quick-repair service.

For clearance gaps greater than 0.2mm we recommend the use of Carbosteam 6550 anti-extrusion rings.


  • Pure expanded graphite yarn
  • High temperature and chemical resistance
  • Extremely dense when compressed
  • Very low leakage
  • Reinforced with Inconel wire
  • High pressure resistance
  • Ideal service packing
  • Quick repair for all valve dimensions


Hot water, steam, gases, oils, acids and alkalis.

Exceptions :strongly oxidizing acids such as sulfuric and nitric acid in high concentrations.

Can be used in combination with CARBOSTEAM 6550 end rings for high-pressure valve applications. Also available with corrosion inhibitor, G-SPEZIAL I 6569.
