PFA (perfluoroalkoxy) tubing offers the broadest chemical resistance of all fluoropolymers. It combines the transparency of FEP with the thermal stability of PTFE, but with a superior smooth inner surface. IDEX PFA tubing is the first choice for applications where ultra-low extraction values and chemical inertness are crucial.

Why choose PFA tubing?
Highest chemical inertness: Virtually unaffected by all known chemicals, acids and solvents. This makes it the safest choice for aggressive fluid streams.
Ultra-low extraction values: PFA contains minimal additives, so there is virtually no risk of leaching, which is essential for trace analysis and ultra-pure processes.
Superior smoothness: The inner wall is smoother than that of PTFE or FEP. This reduces the risk of particle build-up and makes cleaning easier (flushability).
Transparent: Offers excellent visual control over the fluid flow and any air bubbles.
