  • Continuous operation:
    t = -200 °C … +500 °C
  • Steam: tmax = +700 °C

Chemical resistance:
pH = 0 ... 14
Resistant to waste water, sea water, hot water, boiler feed water, condensate, steam, neutral vapors, air, nitrogen, acidic gases, hydrogen, volatile hydrocarbons, oils, mineral oils, fats, heat transfer oils and volatile solvents.


If there are large gaps in the compression packing geometry, we recommend using the Isartherm Flex 6050/KIN as the header ring to avoid gap extrusion.

BuraTAL-Flex 6070

BuraTAL-Flex 6070 is a graphite-based, multi-layered high performance packing It is manufactured from high-purity expanded graphite yarn (>99 %) combined with a newly-developed high temperature impregnation. For long-term stable use in the high temperature range, the packing is additionally finished with a corrosion inhibitor. The multi-layer structure combines the benefits of maximum possible gap bridging due to the inner Inconel wire reinforcement with protection of the high-quality spindle surfaces in the valves. The packing can be installed without special end rings.
