Chesterton 477-1 Multi-Purpose Packing
Innovative PTFE-Coated Carbon Yarn Formulation

  

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​This carbon fiber packing combines a new yarn formulation with superior blocking agents for sealing pumps and valves with one packing.

  • New low-modulus yarn provides the strength associated with continuous filament carbon fibers, plus greater flexibility
  • Strong yet pli​able, without the brittleness of conventional carbon packings
  • Incorporates a high-purity dispersion of inorganic platelets which prevent penetration of gases or liquids through the packing. Interbraid construction locks these blocking agents within the packing
Strong yet pliable, continuous-filament carbon yarn
Unique inorganic blocking agent stops gas/liquid penetration
Molybdenum-based corrosion inhibitor prevents stem pitting​
For use in valve and pumps
Seals most solvents, gases, and other fluids
