Specification :

Graphite packing with carbon fiber corners is a multi-fiber packing, braided from expanded graphite yarns and carbon fibers, the diagonally braided from graphite yarn, reinforced in all four corners with carbon fibers. The corners and body make the packing three times more resistant to extrusion and increase the pressure handing capabilities compared to traditional graphite packings.
