A world of packings, seals gaskets & lubricants

NA 760 - Aramid Fibre + PTFE Fibre Braided Rope

Multi-yarn packing made from pure aramid fibres with corners of pure expanded pre-lubed PTFE fibres at the running surface

  • The expanded pre-lubed PTFE fibres yarns at the base provide excellent chemical resistance, low co-efficient of friction and virtually eliminate shaft scoring
  • The tough PTFE impregnated aramid fibre yarns at the corners provides superb extrusion, abrasion and pressure resistance, allowing the packing to be used at very high pressure conditions
  • Clean and non-toxic, can be used over a wide range of media including critical services that demand an extrusion resistant or reinforced packing

Available in rope and prepressed ring form.
