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.
