Advantages of PTFE for Flexible Hoses

PTFE is an ideal material for flexible hoses, to which a wire over-braid is added for excellent pressure ratings. Such hoses gives extremely long life because its inner core has out-standing resistance to steam, chemicals, solvents, heat pressure impulses, flexing, vibration and aging.

  • Flexible : PTFE hoses will stand up under severe conditions of continuous flexing and vibration without failure from flex fatigue.
  • Chemical resistant : Inert PTFE creates a nearly "Universal" hoses, capable of handling the broadest range of applications except the molten alkali metals such as sodium and potassium, and fluorochemicals such as chlorine trifluoride, oxygen difluoride and fluorine gas.
  • Non-stick : Hoses is easily cleaned, to maintain batch purity when using one hoses for several services.
  • Low friction : Hoses exhibits low pressure drop, which remains constant because no deposits accumulate on inside walls.
  • Temperature resistant : Even handles 180°C steam alternating with cold water.
  • Moisture resistant : Ideal for pneumatic systems requiring low dew point.
  • Non-aging : Properties of hoses do not change with age or exposure to weather.
  • End connections : Swages, Crimped or Reusable type.
