ABSTRACT:
A packing material for formation of a seal for a rotary or reciprocating shaft is disclosed wherein a core element is enveloped by a sheet of expanded graphite material. The core element is preferably formed of a wire mesh and solid graphite. The enveloping process is accomplished in such a manner as to wrap the core element with a self-lubricating surface material. The packing material of the present invention provides the advantages of graphite packings and metallic core packings.
