PFA (Perfluoroalkoxy)
PFA (perfluoroalkoxy) is the tubing of choice for applications involving extreme chemical resistance combined with high temperature exposure.
Altaflo® 400 PFA tubing and pipe are made exclusively from the highest molecular weight resins available giving them superior physical properties.
Altaflo® 400 tubing is suitable for even the most demanding applications.
Altaflo® 400 pipe may be used with conventional threaded fittings or welded.
Altaflo® 400 is compatible with flare or conventional type fittings.
For applications where reduced permeation is critical, please contact Altaflo for information on our new Low Permeation PFA Tubing.
For Semiconductor and other high purity applications, please view our Altaflo® 480 UHP PFA Tubing and Pipe information.
