NA 781L

A pure PTFE filament packing impregnated with PTFE dispersion and with break-in lubricant in interlock braid

  • Manufactured from the purest PTFE yarns to give a soft resilient packing with high dimensional strength, low co-efficient of friction, good chemical resistance and inertness to most media
  • Special PTFE impregnation and added break-in lubricant enables the packing to perform with less friction Special PTFE impregnation and added break-in lubricant enables the packing to perform with less friction
  • Ideal for moderate shaft speed applications
