Independent sourcing partner
PTFE Tubing Sourcing is an independent sourcing partner for US business buyers of ptfe tubing. We do not extrude tube, hold a warehouse, or publish a price list. The buyer still decides inner and outer diameter, wall, length and the documents that must travel with the lot.
A usable brief names the form (unreinforced, reinforced, thin-wall, clear or cut-to-length), quantity by configuration, destination state or postal code, and requested delivery window. Neighbouring wording such as extruded or convoluted tube is not treated as a stocked SKU on this page.

Same-basis list issued to more than one plant
These cards are request fragments, not a datasheet portal we host. A plant brochure is not a lot file. A company certificate is not a dimensional page for the quoted tube.
Ask the supplier to attach the current TDS and SDS that name the quoted grade. Shore A is the wrong hardness scale for PTFE tube; do not copy an elastomer card onto this line.
| File | TDS + SDS on the quoted item |
|---|---|
| Not accepted | Plant ISO certificate alone |
Inner and outer diameter belong together. Wall thickness stays in inches or millimetres. “Standard tube” is not a size.
| ID / OD | Paired, same unit system |
|---|---|
| Wall | in or mm, not “thin” alone |
Coil length, cut-to-length pieces and leftover scrap are different goods. Ask the factory to write packing: coil, stick or bag.
Send the missing axesThe cells below are questions for the factory. They are not PTFE Tubing Sourcing ratings for any option. If two plants answer different walls or different temperature methods, treat them as different goods.
| Thermal | Chemical | Mechanical | Compliance |
|---|---|---|---|
| Service temperature in °F or °C with the medium | Named medium; do not assume “chemical resistant” | ID/OD pair and wall in in or mm | REACH / RoHS statement on the quoted grade if the receiving plant asks |
| Continuous versus short-term exposure, written by the factory | Food-contact file only if it names grade and lot | Reinforcement present or absent; braid is a different form | FDA 21 CFR 177 only when the file cites the quoted resin |
| Do not reprint a brochure range as this desk’s figure | PFAS questions stay with the buyer’s receiving policy | Bend or convolution is a named form, not a default | USP Class VI only if the buyer asked and the lot file exists |
Application names help the factory understand duty. They do not become a promised result. The buyer still writes temperature, medium and documents.
Representative part: liner or guide tube. Ask ID to match the filament path and service temperature at the hot end. A search string is not a drawing.
Representative part: unreinforced or thin-wall tube. Ask the medium and whether reinforcement is required. Do not copy a hose pressure card onto virgin PTFE tube unless the factory writes it.
Representative part: cut-to-length sticks. Ask piece count, cut tolerance and packing. Leftover coil is a different line.
Representative part: clear or translucent tube. Optical clarity is a visual ask, not a density figure this desk can publish.
Representative part: named food-contact grade. The file must cite the lot. A plant brochure is not enough.
Representative part: reinforced tube if the factory offers it. IATF 16949 belongs to the plant, not to this desk.
No named buyer, savings percentage or completed shipment is on file. The cards below are checklists a purchasing team can reuse.
Situation: a plant wants a Bowden liner and only has a printer model number.
Check: write ID/OD and temperature; do not let a salesperson convert the model into “close enough” tube.
Situation: two plants quote different walls for the same ID.
Check: treat them as different goods; re-issue the line with both walls visible.
Situation: a cheaper number arrives on a different Incoterm.
Check: compare total procurement cost on the same packing and document set. Do not recast the gap as a market discount.
