Chesterton GraphMax Packing

Chesterton GraphMax Packing

Structurally-Reinforced Graphite Packing Ideal for Demanding Applications

  

​​​​​​​​Chesterton GraphMax is an interbraided graphite packing. Carbon yarns are incorporated in the braided structure in a way that allows very tight braiding a​nd corner reinforcement that improves the strength of the packing. This dramatically improves the packing’s resistance to extrusion and blow out, one of the limitations of traditional, flexible, graphite tape packings.

GraphMax can be used in demanding rotating applications such as those in the power, pulp and paper, and ore p​rocessing industries where temperature and pressure resistance can be required in combination with chemical and abrasion resistance.

​ GraphMax's applicability in valves makes it a convenient plant-wide general service packing.
