BuraTAL HT 9650/HT

This packing set consists of braided end rings made of expanded pure graphite with carbon fiber-reinforced corne, high-density expanded pure graphite sealing discs which work as a diffusion barrier, specially impregnated adapter rings made from high-density, expanded pure graphite, and a lower-density sealing ring made from expanded pure graphite with a smooth, friction-reducing coating.
