Graphite packing - GR8800A

Composition

The graphite gland compression packing GR8800A is made with continuous graphite PAN yarns, colloidal graphite and passive inhibitor of corrosion

Characteristics

Special graphite packing PTFE free. The packing is impregnated in three steps: firstly yarn by yarn, during the braiding and on the body at the end. The impregnant compound is PTFE free and rich of inorganic inhibitor of corrosion to minimize the corrosion risks.

Applications

GR8800A is a great graphite packing PTFE free suitable for steam, hydrocarbon and chemical products for static and dynamic applications as feed boiler pumps and soot blowers. Avoid the combustion gases over 450°C.
