Chesterton 5800 WedgeSeal Packing
High Performance, Low Friction, Die-Formed Steam Service Graphite Packing


​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 5800 WedgeSeal™​ Packing sets are manufactured from high-purity graphite. The die-formed rings are non-absorbent and non-wicking. A corrosion inhibitor is incorporated into the rings to help prevent stem pitting. 

At elevated system pressures, Chesterton 5800 reduces stem friction while sealing effectively​​​. It provides critical control valves with limited load capabilities to respond more rapidly and precisely throughout the pressure range. ​

Five-year guarantee is available when used with Chesterton 5150 Live Loading.
