Product Selection
Choose the material and exact model before choosing the size. PTFE RSFR-TFE has a different recovery temperature from polyolefin products. DR, VDF175, VT200 and EPDM are separate materials and must retain their own operating and recovery data. WRSLD is catalog-titled Neoprene Tube, while its material description says cross-linked chlorinated polyolefin; confirm material identity before specifying it as neoprene.

How to Specify Your Requirement
Identify the model first, then compare the supplied dimensions, fully recovered dimensions and installation space. Specify operating conditions, required flame or halogen performance, color, length, quantity and packaging. Certification and test references apply to the stated model and must be matched to the supplied product.
Dimensions are in mm unless another unit is stated. Operating temperature, minimum shrink temperature, full-recovery temperature and aging-test conditions describe different requirements. Keep them separate when selecting and installing the product.
RSFR-TFE — Heat Shrink Teflon Tubing
The PTFE heat-shrink product is separate from ordinary WF tubing. Its catalog shrink temperature is above 350°C and its operating range is -65°C to +200°C; the installation temperature is not a continuous-service rating.

Applications and Installation
Typical use follows the selected model: wire and cable insulation, splice or component protection, environmental sealing, harness identification or specialty fluid exposure. Prepare and clean the substrate, protect heat-sensitive components and use controlled heating appropriate to the exact product. Check complete recovery and adhesive flow where applicable.
Frequently Asked Questions
Which model should I choose
Choose the material and exact model before choosing the size. PTFE RSFR-TFE has a different recovery temperature from polyolefin products. DR, VDF175, VT200 and EPDM are separate materials and must retain their own operating and recovery data. WRSLD is catalog-titled Neoprene Tube, while its material description says cross-linked chlorinated polyolefin; confirm material identity before specifying it as neoprene.
Are all models flame retardant
Use the flame-performance statement of the exact model. Halogen-free, low-smoke and flame-retardant are separate requirements. A category title does not establish a shared rating.
How do I choose the size
Select the model and compare its supplied size with the largest assembly dimension and its recovered size with the required final fit. Check wall, tolerances, length and packaging in the corresponding table.
Is shrink temperature the operating temperature
No. Shrink or recovery temperature is an installation condition. Continuous operating temperature and short-duration laboratory aging or heat-shock tests are separate values.
Are all performance values guaranteed limits
Keep the distinction between standard requirements and typical test results shown in the tables. Agree the exact specification, acceptance limits, test method and product documentation with the order.
Can I order custom colors lengths or packaging
Send the exact model, dimensions, color, length, quantity and packaging requirements. Availability and nonstandard options are confirmed with the quotation.
Request a Quote
