PFA Tubing (Perfluoroalkoxy) 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 500º F) and has all the general properties of PTFE.

In the semiconductor and pharmaceutical industries, PFA HP (High Purity) Tubing is used for fluid handling applications requiring an extremely low level of chemical extractables.

PFA Tubing Offers:

  • Higher thermal stability than FEP
  • Working temperature of up to 500º F (260º C)
  • Non-flammable
  • Lower permeability than FEP
  • Combines attributes of PTFE and FEP
  • Translucent
  • Maintains mechanical strength at high temperatures
  • Moisture absorption close to zero
  • Superior high purity properties
  • Availabe in coiled hose and convoluted construtions
  • FDA compliant for food contact
  • Suitable for use with flare or convetional fittings

PFA Tubing Applications:
Aerospace &Transportation Technology, Electronics, Components & Insulators, Chemical & Pharmaceutical Manufacturing, Food Processing, Environmental Sciences, Air Sampling, Fluid Transfer Devices and Water Processing Systems

*This tubing has a safety factor of 5 to 1 (ratio of burst pressure to working pressure). This data is to be used as a guildline only. You should perform actual tests according to your specific application.
**The following equation is for calculating burst pressure. The result from this equation is to be used as a guide line only. The calculation is at ambient room temperature. It does not factor steam pressure, altitude, etc.

B=T(O.D.2 - I.D.2)
     O.D.2 + I.D.2

B=Burst Pressure
T=Tensile Strength Values: FEP-3000 psi    PFA - 4000 psi    PTFE - 2500 psi     PVDF - 5000 psi     ETFE=6500 psi
1 bar = 14.504 psi
