PTFE Tube Inner Diameter Tolerances
Use the required inner diameter, outer diameter, wall thickness, coil length, and application conditions when requesting a quotation.
| Inner Diameter (mm) | Tolerance (mm) |
|---|---|
| 0.2–1.99 mm | ± 0.10 mm |
| 2.0–3.99 mm | ± 0.15 mm |
| 4.0–5.99 mm | ± 0.20 mm |
| 6.0–10.99 mm | ± 0.25 mm |
| 11.0–13.99 mm | ± 0.30 mm |
| 14.0–17.99 mm | ± 0.35 mm |
| 18.0–24.99 mm | ± 0.40 mm |
Tolerance values are general manufacturing references. Confirm the applicable tolerance for the selected grade, production process, wall thickness, and order quantity.
Pressure reference
Pressure Resistance of PTFE Tube
Pressure capability changes with temperature, wall thickness, connections, chemical media, pressure cycling, and required safety factor.
| Size (ID × OD) | Maximum Working Pressure at 20°C (bar) | Burst Pressure (bar) |
|---|---|---|
| 2 × 4 mm | 36 | 144 |
| 4 × 6 mm | 23 | 93 |
| 6 × 8 mm | 16 | 63 |
| 8 × 10 mm | 13.3 | 53 |
| 10 × 12 mm | 10 | 43.5 |
| 12 × 14 mm | 9 | 36 |
Engineering notice: The values above are reference data at 20°C, not a design guarantee. Apply an appropriate safety factor and confirm suitability for temperature, media, fittings, installation, pressure cycling, and applicable standards before use.

Frequently asked questions
PTFE tube FAQ
What should buyers verify when choosing a PTFE tube manufacturer?
Confirm the resin or compound, manufacturing route, dimensional tolerance, inspection method and batch traceability. The drawing and service conditions should be reviewed before price becomes the deciding factor.
What information should I send to a PTFE tube supplier?
Send the required grade, dimensions, tolerance, quantity, operating temperature, chemical media, mechanical load, documentation and delivery destination. Photos or drawings help prevent quotation assumptions.
Can the JAIFUXIN PTFE tube factory make custom sizes?
Custom dimensions and secondary processing can be reviewed from a drawing, sample or application specification. Feasibility depends on the material, production method, tolerance and order volume.
What is the difference between PTFE tube tube, tubing and hose?
Tube and tubing usually refer to products controlled by ID, OD and wall thickness. Hose may imply greater flexibility or reinforcement. Confirm dimensions, pressure rating and construction instead of relying on the name alone.
Is Teflon the same as PTFE?
Teflon™ is a brand name commonly associated with PTFE, while PTFE is the generic polymer name. Buyers should specify the actual resin grade and required properties rather than rely on the trade name alone. See the PTFE material guide.
What is the difference between virgin PTFE and filled PTFE?
Virgin PTFE emphasizes chemical resistance, low friction and electrical insulation. Glass, carbon, graphite or bronze fillers can improve selected wear, creep or load properties but also change other characteristics.
How do I select the right PTFE tube for my application?
Select PTFE tube by pressure, temperature, media, wall tolerance, bend radius, purity and connection method. Final suitability depends on the complete operating environment and required service life.
Which ID, OD and wall tolerance should I specify for PTFE tube?
Specify inside diameter, outside diameter, wall thickness and tolerance together. Pressure, connection method and bend radius may change the practical wall requirement.
How do pressure and temperature affect PTFE tube?
Working pressure normally decreases as temperature rises. Final selection should use the actual fluid, temperature, pressure cycle, wall thickness and safety factor rather than a room-temperature value alone.
Can I order samples before repeat production of PTFE tube?
Samples and prototypes can be reviewed before a production order. Approval criteria should identify critical dimensions, appearance, material grade and any required test records.
