Gland Packing
Aramid Corner-yarn Graphite PTFE Braided Packing
Braided from special wear-resistant aramid fiber corner yarn and graphite-filled PTFE yarn, effectively combining aramid’s wear resistance with graphite-PTFE’s self-lubrication and wear resistance. Low friction and high lubricity, stable against acid, alkali and solvent. Good self-lubrication reduces shaft wear while aramid keeps the packing strong and tough; PTFE emulsion impregnation adds corrosion resistance, especially suitable for ash pumps and slurry pumps.
