Product Style Number & Name:
PA1000 Expanded graphite packing
PA1000C Graphite packing with corrosion inhibitor
PA1000 Expanded graphite packing
Braided from low sulphur expanded graphite yarns which are reinforced by cotton fiber or glass fiber. The packing shows good thermal conductivity, chemical resistance, and high elasticity. In addition, it has low friction factor and does not damage the shafts or stems.
PA1000C Graphite packing with corrosion inhibitor
The corrosion inhibitor acts as a sacrificial anode to protect the valve stem and stuffing box.
Applications:
PA1000 & PA1000C are multi-service packings capable of a wide variety of uses throughout a plant. They can be used in valves, pumps, expansion joints, mixers and agitators in high temperature, high pressure environments of hydrogenation plants, paper mills, power stations, refineries and industries where effective sealing is vital.
A recommended method is to use the graphite packing rings in conjunction with Uni-seals PR1600 carbon fiber anti- extrusion packing rings.
