Chesterton 477-1T Carbon/PTFE Packing

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 477-1T is a tough, yet pliable, continuous filament carbon yarn packing impregnated throughout with PTFE to provide a non-contaminating, non-staining carbon yarn packing.  Developed for the tough applications in the pulp and paper industry, 477-1T is specially designed to be used in high pressure feeders, pre-steaming vessels and applications that are moving abrasive slurries. This packing’s combined force of carbon yarn and PTFE dispersions increases its chemical resistance against strong caustic and acid mediums.

Chesterton 477-1T is also an excellent bottom anti-extrusion end ring when coupled with Chesterton 1400R Carbon-Reinforced Graphite Packing​ in rotating equipment. This combination is ideal for reducing or eliminating flush water from a stuffing box.
