Precision Engineered PTFE Tubing for Demanding Industrial Applications
In the world of fluid handling and chemical processing, the integrity of your transfer lines is non-negotiable. PTFE tubing, crafted from Polytetrafluoroethylene, stands as the undisputed champion for applications where chemical resistance, high-temperature performance, and non-stick properties are paramount. Unlike conventional tubing materials, PTFE offers a unique combination of inertness and durability, making it an essential component across pharmaceuticals, food and beverage, semiconductor manufacturing, and automotive industries. At Kaxite Sealing, we specialize in manufacturing high-performance PTFE tubes that meet the most rigorous standards, ensuring reliability, safety, and longevity in your critical processes.
Our commitment at Kaxite Sealing goes beyond simply supplying tubing. We provide engineered solutions. Every batch of our PTFE tubing is produced with meticulous attention to detail, from the selection of pristine raw materials to the final quality inspection. We understand that a failure in a fluid line can lead to significant downtime, safety hazards, and product loss. Therefore, our tubes are designed to offer exceptional resistance to a vast array of aggressive chemicals, withstand extreme thermal cycling, and maintain purity in sensitive applications. Whether you require standard sizes or custom-configured tubing assemblies, our technical expertise is at your disposal to ensure optimal performance for your specific application.

PTFE Tubing: Frequently Asked Questions (FAQ)
Q: What is the maximum pressure your PTFE tubing can handle?
A: The pressure rating of PTFE tubing depends on the inner diameter, wall thickness, temperature, and fitting type. As a general guideline, our standard tubing with a 1mm wall can handle working pressures up to 150 psi (10 bar) at room temperature. For higher pressure applications, we offer reinforced PTFE tubing or can recommend specific wall thickness increases. It is crucial to consult our engineering team for pressure ratings at elevated temperatures, as the strength decreases as temperature rises.
Q: Can Kaxite Sealing PTFE tubing be used for ultra-pure water systems?
A: Absolutely. We offer a specific high-purity grade of PTFE tubing that is manufactured and handled in a cleanroom environment to minimize particulate and ionic contamination. This tubing features extremely low extractable levels and is ideal for semiconductor UPW (Ultra-Pure Water) systems, pharmaceutical WFI (Water for Injection) lines, and critical analytical instrument feed lines.
Q: How does PTFE tubing compare to FEP or PFA tubing?
A: PTFE, FEP (Fluorinated Ethylene Propylene), and PFA (Perfluoroalkoxy) are all fluoropolymers with excellent chemical resistance. PTFE has the highest continuous use temperature (260°C) and is the most chemically inert. FEP is melt-processable, making it easier to thermoform and weld, but its max temperature is lower (200°C). PFA shares similar high-temperature resistance with PTFE and is also melt-processable, offering excellent clarity. Kaxite Sealing provides all three materials; the choice depends on your need for temperature, clarity, formability, and cost.
Q: Is your tubing suitable for food contact and medical applications?
A: Yes. Kaxite Sealing produces special grades of PTFE tubing that are fully compliant with FDA (Food and Drug Administration) regulations under 21 CFR 177.1550 for repeated food contact. For medical and pharmaceutical applications, we offer USP Class VI compliant tubing, which has passed rigorous biological safety tests for implantation and is suitable for drug transfer and medical fluid handling.
Q: Can the tubing be bent or shaped without kinking?
A: PTFE tubing is semi-flexible. It can be bent to a minimum bend radius, which is typically 5 times the outer diameter of the tube. Bending beyond this radius may cause kinking or flattening, which restricts flow. For applications requiring tight bends, we recommend using pre-formed bent tubes or bend supports. Our technical team can advise on the optimal bending procedure for your specific tube size.
Q: What is the best method to connect or fit your PTFE tubing?
A: Several reliable connection methods exist. For leak-tight, removable connections, compression fittings with ferrules (e.g., Swagelok-type, Parker CPI) are most common. For permanent connections, flaring or welding (for compatible fluoropolymers like PFA) can be used. Kaxite Sealing can also supply custom tube assemblies pre-fitted with your specified connectors, tested and ready for installation, saving you time and ensuring system integrity.
Q: Does Kaxite Sealing offer colored or striped PTFE tubing for identification?
A: Yes, we provide custom color-coding options. Standard PTFE is naturally opaque white. We can produce tubing in various solid colors (blue, red, yellow, green, etc.) or with longitudinal stripes for easy line identification in complex systems. This is particularly useful in chemical plants, laboratories, and multi-line fluid systems to prevent cross-connection errors.
