PVDF Heat Shrink Tubing 2:1 — Black & Clear, Ø0.8mm to Ø25.4mm

Measure the outer diameter of the component you need to cover, then select a tubing size whose recovered (shrunk) diameter is slightly smaller than that measurement. With a 2:1 shrink ratio, the tubing will shrink to approximately half its supplied diameter. For example, Ø6.4mm (≈1/4") tubing will recover to roughly Ø3.2mm. Always allow a small margin for a snug, secure fit.

Quick inch reference: Ø0.8mm ≈ 1/32" | Ø1.6mm ≈ 1/16" | Ø3.2mm ≈ 1/8" | Ø6.4mm ≈ 1/4" | Ø9.5mm ≈ 3/8" | Ø12.7mm = 1/2" | Ø19.1mm ≈ 3/4" | Ø25.4mm = 1"

PVDF heat shrink tubing typically requires a higher activation temperature than standard polyolefin tubing — generally around 175°C (347°F) or above. A heat gun set to the appropriate temperature range is recommended. Avoid open flames, which can cause uneven shrinkage or surface damage.

Yes. PVDF (polyvinylidene fluoride) is generally recognized for strong UV resistance, moisture resistance, and broad chemical compatibility, making it well-suited for outdoor installations, marine environments, and industrial applications where exposure to solvents or fuels is a concern.

PVDF is typically resistant to a wide range of chemicals including acids, bases, hydrocarbons, and many organic solvents. It is commonly used in chemical processing, laboratory, and aerospace applications. For specific chemical compatibility, please contact us to confirm suitability for your application.

Both colors share the same PVDF material properties and 2:1 shrink ratio. The transparent variant allows visual inspection of the underlying component (e.g., wire color, connector markings) after installation, while the black variant provides a cleaner finished appearance and additional UV shielding in outdoor settings.

PVDF heat shrink tubing is generally used for mechanical protection, chemical resistance, and bundling rather than as a primary electrical insulator in high-voltage applications. For standard low-voltage wire identification and strain relief, it is commonly used in aerospace, automotive, and electronics wiring. Confirm dielectric requirements with your application specs before use.

Use sharp scissors or a utility knife for clean, straight cuts. PVDF tubing is firmer than standard polyolefin, so a sharp blade ensures a clean edge without fraying. Cut slightly longer than needed — typically 5–10mm extra on each end — to account for any end pull-back during shrinking.
