  FAQ:

• 1. What is PTFE capillary tube?

  PTFE capillary tube is a small-diameter tube made from polytetrafluoroethylene. It is also called Teflon tubing, PTFE micro tubing or PTFE insulating sleeve. It is commonly used for electrical insulation, wire protection, chemical transfer, air lines, laboratory equipment and precision instruments.

  2. What is the difference between PTFE tube and Teflon tube?

  PTFE is the material name, and Teflon is a commonly used trade name for PTFE material. In many industrial applications, PTFE tube and Teflon tube refer to the same type of fluoropolymer tubing.

  ---

  3. What are S-Type, T-Type and L-Type PTFE tubes?

  S-Type, T-Type and L-Type usually refer to different wall thickness options of PTFE tubing. For the same AWG size and inner diameter, the outer diameter may be different depending on the type.

  Generally:

• S-Type: thicker wall
• T-Type: medium wall
• L-Type: thinner wall

• The final choice depends on insulation requirement, flexibility, pressure condition and installation space.

  4. What AWG sizes are available for PTFE tubing?

  We supply standard AWG PTFE tubing from AWG 30 to AWG 0. The inner diameter range is approximately 0.30 mm to 8.38 mm. Different outer diameters are available for S-Type, T-Type and L-Type.

  Custom OD, ID and wall thickness can also be produced according to customer requirements.

• 5. What is a PTFE tube?

• A PTFE tube is a plastic tube made from polytetrafluoroethylene. It is known for high temperature resistance, chemical resistance, low friction and excellent electrical insulation. PTFE tubes are widely used in chemical transfer, wire protection, air lines, laboratory equipment and industrial applications.

  6. Is PTFE a Teflon?

  PTFE is the material name, while Teflon is a well-known trade name often used for PTFE products. In many applications, people use “PTFE” and “Teflon” to refer to the same fluoropolymer material.

  ---

  7. Is PTFE tube the same as Teflon tube?

  In most industrial use, PTFE tube and Teflon tube refer to the same type of tubing. PTFE describes the material, and Teflon is a common trade name associated with PTFE-based products.

  ---

  8. Is PTFE hose Teflon?

  A PTFE hose is often called a Teflon hose because the hose liner is made from PTFE material. However, the full hose structure may also include stainless steel braid, rubber cover or other reinforcement layers depending on the application.

  ---

  9. What is PTFE tubing used for?

  PTFE tubing is used for chemical transfer, electrical insulation, wire protection, air and gas lines, laboratory equipment, precision instruments, 3D printers and high temperature industrial systems.

  ---

  10. What temperature can PTFE tubing withstand?

  PTFE tubing can typically work from about -60°C to +260°C. It is suitable for many high-temperature applications, but the actual working limit may depend on pressure, tube size, medium and installation conditions.

  ---

  11. Is PTFE tubing chemical resistant?

  Yes. PTFE tubing has excellent resistance to many acids, alkalis, solvents and corrosive chemicals. It is commonly used in chemical equipment, laboratory systems and industrial fluid transfer.

  ---

  12. Is PTFE tubing flexible?

  PTFE tubing has moderate flexibility. It is not as soft as silicone or PVC tubing, but it offers better high temperature resistance, chemical resistance and electrical insulation. For better transparency or flexibility, FEP or PFA tubing may also be considered.

  ---

  13. Can PTFE tube be used for electrical insulation?

  Yes. PTFE tube is widely used as an electrical insulation sleeve for wires, cables, sensors and electronic components. It performs well in high temperature and chemically harsh environments.

  ---

  14. What is the difference between PTFE, FEP and PFA tubing?

  PTFE tubing has excellent high temperature resistance, low friction and insulation performance. FEP tubing is more transparent and flexible. PFA tubing offers better high-purity performance and is suitable for more demanding chemical and semiconductor applications.
