Graphite packing reinforced with wire is braided from expanded graphite yarns, reinforced with metal wire, normally reinforced with inconel wire. It retains all the inherent benefits of flexible graphite packing. The wire reinforcement provides greater mechanical strength, used for high pressure and temperatures.
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.
