Hollow Core Packing
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.
