When it comes to transporting ozone gas and other corrosive substances, FEP tubing stands out as the best option available. At Oxidation Technologies, we offer high-quality FEP tubing (1/4″ ID x 3/8″ OD) that delivers exceptional performance, durability, and chemical resistance. Its transparent design, flexibility, and high tolerance to extreme temperatures make it the ideal solution for a wide range of applications.
Why FEP Tubing is the Best Choice for Ozone Gas
FEP tubing is a copolymer of TFE (tetrafluoroethylene), modified to enhance its strength and performance. Compared to PTFE tubing, FEP tubing offers several key advantages:
- 30% higher working pressure
- Transparent walls for easy monitoring of flow
- Higher stiffness for better structural integrity
- Lower use temperature (by 50°F) while maintaining high chemical resistance
These properties make FEP tubing particularly well-suited for ozone gas transport, as it resists breakdown from ozone exposure and maintains its integrity under harsh conditions.
Flexible and Easy to Use
Our FEP tubing is highly flexible and can be easily cut to size or shaped to fit specific applications. Unlike other fluoropolymer tubing, FEP can be produced in long continuous lengths through extrusion, making it more cost-effective and easier to install.
We keep FEP tubing in stock for our own use when building ozone systems, and we also offer it for sale. Tubing is available in any length you require — simply contact us if you need specific coil lengths or spools, and we’ll do our best to meet your needs.

Key Advantages of FEP Tubing
- Cost-Effective Alternative to PTFE – FEP tubing offers similar performance to PTFE at a lower cost.
- Excellent UV Transmission – High transparency and UV resistance make it ideal for environmental and sterilization applications.
- Superior Mechanical Properties – Higher working pressure and tensile strength ensure better durability and performance.
- Longer Continuous Lengths – FEP tubing can be produced in longer lengths through extrusion, simplifying installation.
- Broad Temperature Range – With a service temperature range from -418°F to 403°F, FEP tubing performs well in extreme environments.
- Clear Tubing for Easy Monitoring – Transparency allows you to monitor flow and detect any issues quickly.
Compatible with Kynar Fittings
For best results, we recommend using FEP tubing with Kynar fittings. Kynar fittings are designed to create a tight, secure seal around plastic tubing and are resistant to both abrasion and corrosion. They are available in various sizes and specifications, making them easy to integrate into your existing system.
Applications of FEP Tubing
FEP tubing is widely used in various industries due to its chemical resistance, transparency, and flexibility:
- Ozone gas transport
- Water disinfection
- Cabling and electrical insulation
- Food contact and processing
- Environmental testing
- High-purity chemical transfer
