FEP Fluoropolymer Tubing

FEP (Fluorinated Ethylene Propylene) tubing is an optically clear, chemically inert fluoropolymer tubing designed for general, low-pressure fluid transfer in analytical, life science, medical, and industrial applications. With an exceptionally wide operating temperature range from -200°C to +200°C, FEP delivers reliable performance in both cryogenic and elevated-temperature environments.

Known for its excellent UV transmission and low gas permeability, FEP tubing is ideal for applications where visual flow confirmation is important. Most FEP options—including color-tinted tubing—remain translucent, allowing operators to monitor fluid movement in real time. Black FEP is available for light-sensitive workflows such as enzymatic reactions, chemiluminescence, and flow cell connections.

FEP offers outstanding resistance to acids, bases, and organic solvents while remaining flexible and easy to route. Its smooth internal surface supports consistent flow paths, making it a versatile choice for HPLC plumbing, analytical instrumentation, food and beverage processing, aerospace systems, and laboratory automation.

Chrom Tech supplies high-quality FEP fluoropolymer tubing manufactured to tight dimensional tolerances, ensuring dependable connections and repeatable performance across a wide range of chromatography and fluid handling applications.

Frequently Asked Questions â–¶
What is FEP tubing commonly used for?
FEP tubing is widely used in analytical instrumentation, life science workflows, medical devices, food and beverage processing, and general laboratory plumbing where chemical resistance, transparency, and flexibility are required.
Is FEP tubing suitable for high-pressure HPLC applications?
FEP tubing is typically recommended for low-pressure fluid paths. For high-pressure HPLC or UHPLC systems, materials such as PEEK or stainless steel tubing are preferred.
Can I visually monitor flow through FEP tubing?
Yes. Most FEP tubing options are translucent or optically clear, allowing operators to observe fluid movement. Black FEP tubing is available for light-sensitive applications.
What temperature range does FEP tubing support?
FEP tubing typically operates from approximately −200°C to +200°C, making it suitable for both cryogenic and elevated-temperature laboratory environments.
Is FEP tubing chemically inert?
Yes. FEP offers excellent chemical compatibility with acids, bases, and organic solvents, making it a reliable choice for aggressive or sensitive fluid handling applications.
