PA1000 Expanded graphite packing

The packing is braided from low sulphur expanded graphite yarns, which are reinforced by cotton fiber or glass fiber. With very low friction, it does not damage shafts or stems. It also shows good thermal conductivity, chemical resistance and high elasticity.

PA1000C Graphite packing with corrosion inhibitor

The corrosion inhibitor acts as a sacrificial anode to protect the valve stem and stuffing box.

Application:

PA1000 & PA1000C 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 temperature, high pressure environments of hydrogenation plants, paper mills, power stations, refineries and industries where effective sealing is vital.

Precaution: oxidizing environment.

Recommendation: use preferably with PR1600 carbon fiber anti-extrusion packing rings.
