Chesterton 477-1 carbon fiber packing combines a new yarn formulation with superior blocking agents. New, low modulus yarn provides the strength associated with continuous filament carbon fibers plus greater flexibility. This makes 477-1 strong, yet pliable, without the brittleness of conventional carbon packing.
Chesterton 477-1 incorporates a high-purity dispersion of inorganic platelets which prevent penetration of gases or liquids through the packing. Inter-braid construction locks these blocking agents within the packing ring.
Features & Benefits:
- Strong, yet pliable, continuous filament carbon yarn
- Unique inorganic blocking agent stops gas/liquid penetration
- Molybdenum-based corrosion inhibitor prevents stem pitting
