PFA tube offers excellent crack and stress resistance and is used when more demanding mechanical characteristics are required. PFA Tubing is the product of choice for applications involving extreme chemical resistance combined with high temperature exposure.  PFA Tubing is preferred when additional clarity, flexibility, and a higher continuous service temperature are required. PFA Tubing provides stiffness and long flex-life (up to 500 F) and has all the general properties of PTFE.
