Altaflo® 400 PFA Tubing & Pipe

Extreme chemical resistance and high temperature exposure for superior physical properties

Request More Information

PFA (perfluoroalkoxy) is the tubing of choice for applications involving extreme chemical resistance combined with high temperature exposure. Although PFA is available in a variety of resin grades, Altaflo 400 PFA tubing is made exclusively from the highest molecular weight resins available, giving it superior physical properties, making it suitable for even the most demanding applications. Altaflo 400 Series PFA does not impart taste or odor, is compatible with flare or conventional fittings, and is available as Tubing and Schedule 40 Pipe.

Features

  • 100% virgin grade high-performance resins used to resist stress cracking
  • Chemically inert to nearly all industrial chemicals and solvents
  • Higher thermal stability than FEP
  • Lower permeability than FEP
  • Translucent
  • Moisture absorption nearly zero
  • FDA compliant for food contact
  • Non-flammable
  • Suitable for use with flare or conventional fittings
  • Available in coiled hose and convoluted constructions
  • Higher upper surface temperature vs. FEP

Applications

  • Chemical process
  • Heat exchangers
  • Laboratory applications
  • Semiconductor
  • Flow monitoring
  • Food processing
  • Electrical insulation
  • Automotive
