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.
