Fluid transfer & chemical dosing
Carries aggressive media where the tube must not react with the fluid and must keep a stable bore over time.
WCW ELECTRICAL INSULATION PRODUCT
PTFE Tubing (Non-Shrink)
A non-shrink PTFE tube with a smooth bore that keeps its original dimensions. Used for fluid transfer, chemical dosing and high-temperature routing where chemical resistance and low friction matter.
APPLICATIONS
Applications
Sensor & instrument lines
Protects and routes sensing lines that need clean surfaces, tight tolerances and low friction.
High-temperature routing
Keeps its dimensions where continuous or short-term heat rules out most polymer tubing.
Insulating sleeves over conductors
Slides over rods, probes and inner conductors as a non-shrink dielectric sleeve.

PRODUCT CLARIFICATION
Non-shrink vs. heat shrink
This page covers the non-shrink PTFE tube, which is supplied at its final dimensions and is normally used for fluid transfer and chemical-resistant routing. If the assembly needs the tube to recover onto a component under heat, use our separate PTFE heat shrink tube (2:1) instead.
QUALITY DOCUMENTS
Certifications
RoHS and REACH declarations can be reviewed for the selected PTFE material grade. Final qualification must use the exact tube dimensions, the actual medium and the end-use test method.

Send inner / outer diameter, wall thickness, cut length, operating temperature and medium. Include the target application, annual demand and required qualification files for a faster review.
FAQ
Product selection questions
Is this the same as PTFE heat shrink tube?
No. This is a non-shrink PTFE tube that keeps its original dimensions. A separate 2:1 PTFE heat shrink tube is available when shrink recovery is required.
Can the tube dimensions be customized?
Inner diameter, outer diameter, wall thickness and cut length can all be reviewed against the drawing and the medium being carried.
What should be tested before approval?
Validate inner diameter tolerance, wall concentricity, pressure performance, chemical compatibility with the actual medium, temperature cycle and end-fitting assembly.
