Frequently Asked Questions (FAQ) About PTFE Tube
What is the primary difference between PTFE, FEP, and PFA tubing?
PTFE, FEP (Fluorinated Ethylene Propylene), and PFA (Perfluoroalkoxy) are all fluoropolymers. PTFE has the highest continuous use temperature (260°C) and best chemical resistance but is opaque and more difficult to thermoform. FEP is translucent, melt-processable, and has a lower temp rating (200°C). PFA offers clarity similar to FEP, a high temp rating (260°C), and excellent chemical resistance, often used for high-purity liquid handling. Kaxite Seals can help you select the optimal material.
Can Kaxite Seals PTFE Tube be used for steam applications?
While PTFE has excellent temperature resistance, prolonged exposure to high-pressure, high-temperature steam (e.g., >150°C at significant pressure) can lead to gradual degradation over time. For intermittent or low-pressure steam services, it may be suitable. For critical continuous steam applications, we recommend consulting our engineers for a detailed assessment and potential alternative material suggestions.
How do I connect and fit PTFE tubing? What fittings are compatible?
PTFE tubing is relatively flexible but not elastomeric. Common connection methods include using compression fittings (e.g., Swagelok®, Parker CPI), push-to-connect fittings, or barbed fittings with hose clamps. For a leak-tight seal with compression fittings, it's crucial to use ferrules designed for PTFE or use a combination of a PTFE sleeve with a standard metal ferrule. Over-tightening should be avoided to prevent crushing the tube wall.
Does Kaxite Seals offer PTFE tubing that is reinforced or conductive?
Yes. We offer specialized versions including stainless steel braid-reinforced PTFE hose for higher pressure and vacuum applications, which provides added burst strength and kink resistance. We also supply carbon-filled or metal-particle-filled PTFE tubing that provides static dissipative or conductive properties for applications requiring electrostatic discharge (ESD) protection.
What are the sterilization options for your PTFE tubing in pharmaceutical or food use?
Kaxite Seals PTFE Tube is compatible with all common sterilization methods. It can withstand repeated cycles of autoclaving (steam sterilization at 121-134°C), dry heat, gamma irradiation, and Ethylene Oxide (EtO) treatment without significant loss of properties. Its non-porous surface prevents bacterial entrapment, supporting cleanability and sterility.
How should I store PTFE tubing, and what is its shelf life?
Store the tubing in its original packaging in a cool, dry, dark place away from direct sunlight and heat sources. Avoid extreme bending or crushing during storage. Properly stored, PTFE tubing has an essentially indefinite shelf life as it does not degrade under normal ambient conditions. Its material properties remain stable for decades.
Can you manufacture PTFE tubing with custom colors or printing?
Absolutely. Kaxite Seals offers custom color-coding using FDA-compliant pigments for easy identification of lines in complex systems. We can also provide permanent surface printing or laser marking with part numbers, volume/ length marks, or other identifiers to meet traceability and operational requirements.
