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

Features & Benefits:

  • Strong yet pliable, continuous-filament carbon yarn
  • Unique inorganic blocking agent stops gas/liquid penetration
  • Molybdenum-based corrosion inhibitor prevents stem pitting
