Chesterton 1726 Low Emissions Isolation Valve Packing for Chemical Service
Meets New Reduced Emissions Levels Without Live Loading

  

​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 1726 Low E Packing minimizes isolation valve emissions to help ​companies in the petrochemical, chemical, and oil and gas industries meet and even exceed current emissions requirements.  T​his stem packing can accomplish required sealing levels without the use of costly and time-consuming live loading assemblies.


1726 is uniquely constructed with a combination of PTFE surrounding a carbon core in a true double-braided formation. The PTFE jacket provides chemical resistance and lower friction while the specially formulated carbon core provides superior sealing capability in harsh, corrosive environments. The result is a non-hardening, flexible packing that is extremely strong yet extrusion-resistant, delivering a highly secure and reliable seal for emissions service.
