Specification of Gland Packing Carbon / PTFE Chesterton 477 -IT
Chesterton 477-1T Carbon Packaging / PTFE Chemical Resistant Carbon Yarn PackagingThe Chesterton 477-1T is a tough, yet flexible, continuous filament carbon yarn pack that is impregnated with PTFE to provide a non-polluting and stain-free carbon yarn packaging. Developed for tough applications in the pulp and paper industry, the 477-1T is specifically designed for use in high pressure feeders, pre-steam vessels, and applications moving abrasive slurries. This combined strength of the carbon yarn packing and PTFE dispersion increases its chemical resistance to strong caustic and acid media. The Chesterton 477-1T is also an excellent bottom anti-extrusion end ring when paired with the Chesterton 1400R Carbon-Reinforced Graphite Packing in rotating equipment. This combination is ideal for reducing or eliminating flushing water from stuffing boxes. Non-polluting and non-staining carbon yarn packaging Unique inorganic blocking agent stops gas/liquid penetration Molybdenum based corrosion inhibitor prevents rod holesAlmost all pumps and valves resist most solvents, gases and other liquids. Temperature Limit 260 °C (500 °F) Pressure Limit 14 bar g (200 psig) Shaft Speed 15 m/s (2000 fpm) 15 m/s (3000 fpm) when used as a bottom anti-extrusion ring with Chesterton 1400R Durability Chemical pH 0 to 14 except strong oxidizing agents For further information please contact: Lucky Office : LTC Lt.GF 1 Blok C25 No.7 Jl.
