Typical Applications – PTFE Tubes
Manufacturing Methods – Extruded vs. Molded PTFE Tubes
Extruded Tubes
- ✅ Continuous process for long lengths
- ✅ Tight tolerances on ID and OD
- ✅ Smaller diameters (0.5 – 50 mm ID)
- ✅ Cost‑efficient for medium‑volume orders
Molded Tubes
- ✅ Suitable for large diameters (up to 300 mm ID)
- ✅ Thicker walls (up to 20 mm)
- ✅ Ideal for custom, short‑run orders
- ✅ Excellent dimensional stability
Both manufacturing methods are available at Kaxite – consult us to choose the best option for your application.

Frequently Asked Questions – PTFE Tubes
What is the maximum continuous operating temperature for PTFE tubes?
PTFE tubes can operate continuously at temperatures up to 260°C (500°F), with short‑term peaks up to 300°C. At the low end, they remain flexible down to -200°C.
Are your PTFE tubes FDA‑compliant?
Yes, our virgin PTFE tubes comply with FDA regulation 21 CFR 177.1550 and are suitable for food, beverage, and pharmaceutical contact applications. We also offer USP Class VI grades on request.
Can you supply PTFE tubes with conductive or anti‑static properties?
Absolutely. We offer carbon‑filled, graphite‑filled, and metal‑filled PTFE tubes to provide anti‑static and conductive properties for applications requiring electrical grounding or explosion protection.
What is the minimum wall thickness for extruded PTFE tubes?
We can produce extruded tubes with wall thicknesses as low as 0.25 mm for small diameters, and up to 5 mm for larger sizes. For thicker walls, molded tubes are recommended.
Do you provide custom cutting and flaring services?
Yes, we offer custom cutting to length, as well as flaring, flanging, and heat‑forming services for PTFE tubes. Please provide your specifications for a tailored quotation.

PTFE Tube
Consisting of all characteristics of ptfe, PTFE Tube is an ideal raw material among all plastics. It has internally smooth structure, which made it very strong and flexible. It consists anti friction, anti-brokage and anti-blockage characteristic. It's highly resistant to the corrosive chemicals. It also consists of good dielectric strength and good tensile strength.
