Abstract
The compact five ring stuffing box packing assembly includes high density metal inserted braided end rings of graphite which have each been die formed to have angled facing surfaces. Three low density graphite preform rings having angled facing surfaces are contained between the high density braided end rings. The facing surfaces of the preform rings extend at a different angle relative to the longitudinal axis of the packing assembly than do the facing surfaces of the braided end rings. The braided end rings provide a support function for the preform rings as well as a stem wiping function.
