  • It has the ability to return to 95% of its original shape after having been crushed up to 50% of its original size.
  • It has the ability to run dry without major detrimental effects on the packing.
  • It s resistance to abrasion makes it suitable for applications such as slurries, pulp and the like.

Style 99H has the ability to be crushed up to 50 % and return to 95% of its original shape and size. This means that in an application where a shaft has extreme run out, vibration or sagging, Style 99H can offer a controlled leakage and possibly a leak free application depending on the type of installation.
