tubing & rod



Expanded PTFE (ePTFE) tube is microporous so air-permeable, and is perfect for any applications that require a permeable PTFE tube.


ePTFE tube is extruded by a special process that expands and orientates the PTFE, making it soft and flexible. ePTFE is a unique material offering special properties of importance to many industries.

We offer ePTFE porous tubing in standard sizes, from 2.5mm to 8mm ID, which are produced to order. Find our ePTFE Tubing Sizes.

Being microporous, ePTFE is significantly different to conventional PTFE tubing – the material is air-permeable, soft and flexible, and feels somewhat like smooth, spongey marshmallow to the touch.

  • Chemically resistant with high linear strength

  • Chemically inert

  • Watertight at low pressure

  • Low dielectric constant

  • Excellent radial expansion and UV resistance

  • Completely non-toxic and hygienic
