PFA Linear Tubing


PFA Linear Tubing

Wide range of dimensions: diameters, tolerances and lengths.
Conductive versions of PFA Linear Tubing are available on demand.



PFA Linear Tubing are the ideal solution for low pressure applications where it’s required:

  • high clarity,
  • high temperature resistance,
  • high purity grade,
  • ease of cleaning,
  • good flexibility,
  • long durability and chemical resistance.






Material: Perfluoroalkoxy/PFA

PFA is a high quality melt-processable fluoroplastics entirely fluorinated with high purity.

PFA excels in all the properties and characteristics offered by both PTFE and FEP.
In particular:

Range of working temperatures from -70°C (-95°F) to 260°C (500°F) High clarity and excellent UV Rays resistance
Longer and improved flex-life Lower gas and vapour permeability



Fluoropolymers Chemical Resistance

All Fluoropolymers, and especially PTFE, have excellent chemical properties.
The chemical resistance is nearly overall with only few limitations, which can be summarized as follow:

Fluorinated Hydrocarbons Swelling (reversible after short-term exposure, not reversible after long term exposure)
Alkali metals, in solution or molten state Fluorine elimination/Polymer destruction
Halogens, Elementar Fluorine, Chlorine-Trifluoride At very high temperatures possible chemical reaction with polymer destruction (possible explosion)
Monomers: Styrene, Butadiene and Acrylonitrile Possible penetration/Spontaneous polymerization may destroy the polymer
High energy radiation Gamma radiation: physical properties can be reduced by approx. 50% already with 10kGy dosage
Nitrating acid: mixture of concentrations H2SO4 and HNO3 At high temperatures (>100°C) possible decomposition of the fluoropolymer
