FEP tubing is a copolymer of TFE, the basic fluoro-monomer building block. The addition of a modifier results in a small, but meaningful departure from the properties of PTFE tubing. Mainly, it possesses a working pressure that is 30% higher, transparent walls, a small increase in stiffness, and a use temperature that is 50 degrees F lower.

Unlike other fluoropolymer tubing, long continuous lengths of FEP tubing can also be produced by extrusion. The relatively low cost and desired properties of FEP tubing drives its use in many applications that require high electrical breakdown voltage, low dielectric constant, high chemical resistance, high UV transmission, excellent sterilizability and longevity of use.

FEP tubing is best used with Kynar Fittings which are specially designed to create a tight seal around plastic tubing. These fittings come in a variety of sizes and specifications and are resistant to abrasion and corrosion.


Key Properties:

     -Cost-effective fluoropolymer and alternative to PTFE

     -Excellent UV transmission, electrical, and better mechanical properties than PTFE

     -Longer continuous tubing lengths available compared to PTFE

     -Great for cabling, electrical insulation, water disinfection, environmental, and food contact applications

     -Preferred material where tubing clarity or organization is desired

     -Use temperature of 450 F (~230 C)
