Braided from graphite fiber-reinforced flexible graphite yarns and high purity graphite filament yarns to provide high tensile strength, low friction, and excellent heat dissipating properties
Premium flexible Graphite (FG) packing with field proven performance and reliability. The packing material is reinforced with high purity graphite fiber yarn giving it superiority over other lower performing reinforcement materials.
The placement of the graphite filament yarns adds abrasion resistance for rotary services and anti-extrusion resistance for valve applications. The versatility of 1333-G can result in significant savings in inventory investment.
