FEP Convoluted Tubing

 FEP Convoluted Tubing is available in Convo-Flon (see chart 1 below) or Convo-Flex ™(dimensions similar to our PTFE Convo-Tex®, see chart 2 below) and operates in temperatures up to 400°F/204°C.  It  is ideal for applications where visibility or long lengths are required.  Because  FEP convoluted tubing  is almost clear, it allows operators to watch and monitor the material passing through the tube.  In addition, because  FEP is a thermoplastic material, tubing coils can be supplied in much longer lengths than with the  PTFE Convoluted Tubing.  

If you need the attributes of  PTFE  temperatures (up to 500°F/260°C) and the clarity of  FEP we also offer  PFA and MFA.  All of the sizes listed for the different varieties of convoluted tubing can be supplied in most of the resins we offer.  Just ask us for assistance and we will be happy to guide you through the attributes and limitations of each material.
