    PTFE Assemblies

    Teflon, or Polytetrafluoroethylene (PTFE), to give it its full chemical name, was discovered by DuPont scientist Dr. Roy Plunkett. It is a plastic resin in the Fluorocarbon group, and is an ideal problem solver for fluid transfer applications involving aggressive chemicals, extremes of temperature/movement or where hygiene is paramount. Key properties
    include:

      • A wide operating temperature range (-60°C - +260°C)
      • Inert to virtually all chemicals
      • Resistance to weathering/ageing: unaffected by UV light, resistant to oxidation, surface fouling and discolouration
      • Non-flammable
      • Lightweight
      • Superior fatigue flex
      • Low permeability
      • Lowest coefficient of friction of any solid material known to man
      • Unlimited shelf life

    The PTFE Hose liner is virtually inert to all chemicals and solvents. It is resistant to fuiming Sulphuric and Nitric acids,
    Amines, Antioxides and Methanol. It is only known to react with elemental Alkali metals (molten or in solution), Fluorine
    and Chlorine Trifuoride.

    Hose

    PTFE

    Temp Range

    : -60°C - +260°C

    Hydraflex PTFE smooth bore hose bore is manufactured from Teflon/PTFE. No pigments or additives are incorporated. The wire braiding (1 or 2 wire available) is produced from AISI 304/S15 or BS970-1 1996 quality hard drawn tensile stainless steel wire. Anti-static (carbon) versions of all hoses are available for electrically resistive fluids which are being transferred at high rates.

    Hydraflex PTFE convoluted hose was originally designed for easy assembly by re-sellers looking to de-convolute the hose when using standard hydraulic inserts. A range of ferrules to suit this product is available in assembly form from our Assemble Division. Anti-static (carbon) versions of all hoses are available for where electrically resistive fluids are being transferred at high flow rates.

    STATIC APPLICATIONS
    To prevent the build up of static, especially on longer lengths and where high velocities are involved, and the potential damage it can cause to a hose an anti static version is available on request.

    TAPE WRAPPED PTFE
    Combining extreme flexibility of application, corrosion resistance, long term durability and chemical inertness, this hose can be used in many diverse applications including   chemical transfers, food handling, processing applications from pure water to hazardous waste.

    TAFTED ASSEMBLIES
    This is where the PTFE liner comes through the fittings to encapsulate the assembly providing a fully chemical resistance solution
