Description Braided from low-sulphur expanded graphite yarns, which are reinforced by cotton or glass fiber. It has a very low friction, does not damage shafts or stems. It shows good thermal and chemical resistance and high elasticity. Construction Other reinforcement materials are also availableGlass fiber****-High strength, lower costCarbon fiber***-Less weight lossQS***0K *-Flexible Packing with Corrosion InhibitorCorrosion inhibitor acts as a sacrificial anode to protect the valve stem and the stuffing box. Application QS***0 & QS***0K 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, high-temperature hostile environments of hydrocarbon processing, pulp and paper, power stations, refineries and industries where effective sealing is vital.Precaution in oxidizing ***** Use preferably with QS***2 high carbon fiber anti-extrusion packing rings.
