Chesterton Gland Packing 477-1
Chesterton Gland Packing 477-1 Packing Chemical Resistant Carbon Yarn
Chesterton 477-1T is a tough, but flexible packaging carbon filament yarn
impregnated along with PTFE to provide non-contamination, non-coloring
carbon yarn packaging. Developed for applications that are difficult on pulp and paper
industry. Series 477-1T is specifically designed for both stationary and swivel use
applications include high pressure feeders, pre-steamed vessels, and applications
which drives the abrasive porridge. The combined strength of this carbon thread
and PTFE dispersion increases its chemical resistance to strong caustic
and acidic medium.
