FAQs: FEP Tubing

FEP tubing, or fluorinated ethylene-propylene tubing, is a type of plastic tubing made from a copolymer of tetrafluoroethylene (TFE). Known for its high chemical resistance and durability, FEP tubing offers a versatile solution across a range of industries. It was developed as an alternative to PTFE (polytetrafluoroethylene) tubing, which, while chemically resistant, is less flexible and more difficult to process. FEP tubing is transparent by default but can also be manufactured in various colors for easy system identification.

FEP tubing is commonly used in applications that require both chemical resistance and the ability to withstand a wide range of temperatures. These include the biopharmaceutical and laboratory industries, where clean, non-reactive transport of fluids is essential. It performs particularly well in low-pressure environments and is a cost-effective option compared to other high-performance materials.

The primary difference between FEP and PTFE tubing is that FEP is melt-processable. This makes it much easier to fabricate, cut, and form into complex shapes or lengths, which is a major advantage in manufacturing and installation processes. While it shares many of PTFE's beneficial properties, FEP does have a slightly lower maximum operating temperature of +200°C.

Flexibility is one of FEP tubing’s key strengths. It can be cut and reshaped easily, and its compatibility with push-to-connect fittings makes it simple to install and maintain. These properties make FEP tubing a practical and reliable choice for systems that require durable, chemically inert, and temperature-resistant tubing solutions.
