Description Flexible graphite packing braided from expanded graphite yarns, reinforced of cotton fiber, glass fiber, carbon fiber, etc. It has good thermal and chemical resistance and high elasticity. Low friction does not damage shafts and stems.
HV400K -- Flexible Graphite Packing with Corrosion Inhibitor Corrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box.
Typical Application > Flexible graphite packing is a multi-service packing capable of a wide variety of uses throughout a plant.
> It can be used in valves, pumps, expansion joints, mixers and agitators in high-pressure and temperature.
> Effective sealing is vital.
Prime Features > Reinforced with glass fiber: high strength, lower cost
> Reinforced with carbon fiber: less weight loss
> Good thermal and chemical resistance and high elasticity.
