Yellow PVC Heat Shrink Tubing — 9mm to 180mm Flat Width, 1m to 200m Rolls

Measure the outer diameter of the object you want to cover, then select a variant whose Ø (inner diameter) value is slightly larger than that measurement. For example, a cable with a 10mm outer diameter generally fits well inside the 17mm flat-width tubing (Ø10.8mm recovered ID). When in doubt, size up — PVC heat shrink tubing generally cannot be re-expanded once shrunk. Ordering a 1m sample is a low-cost way to verify fit before committing to a longer roll.

Quick reference: flat width ÷ π ≈ recovered inner diameter. So a 9mm flat width gives approximately Ø5.7mm, and a 50mm flat width gives approximately Ø31.8mm.

PVC heat shrink tubing of this type typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. The Ø values listed in each variant name reflect the recovered (post-shrink) inner diameter. The tubing does not typically shrink significantly in length during the process.

PVC heat shrink tubing generally activates at temperatures between 70°C and 90°C (158°F–194°F). A heat gun on a low or medium setting, a hot-air rework station, or a lighter held at a safe distance all work well. Move the heat source steadily along the tubing to shrink it evenly. Avoid holding a direct flame in one spot, as this can scorch or melt the PVC surface.

PVC heat shrink tubing provides basic moisture resistance and is generally suitable for indoor and light-duty outdoor use — for example, protecting wire connections in a garden shed, RC vehicle, or outdoor lighting installation. For prolonged UV exposure, submersion, or harsh weather conditions, an adhesive-lined polyolefin tubing is typically a more durable choice.

Yes. PVC heat shrink tubing is generally compatible with copper wire, aluminum wire, and most standard PVC or XLPE cable jackets. It is commonly used for insulating solder joints, protecting crimp terminals, bundling multi-conductor cables, and color-coding wire runs in automotive, electronics, marine, and hobby applications. It is not typically recommended for use with silicone-jacketed wire in high-temperature environments.

The 1m and 3m options are ideal for one-off repairs, prototyping, or testing fit before committing to a size. The 5m length suits small project batches. The 50m, 100m, and 200m rolls offer a lower per-meter cost and are suited for production runs, workshop stock, or ongoing projects where you use the same size repeatedly. In most cases, buying a 1m sample first is a practical way to verify the correct diameter before ordering in bulk.

PVC heat shrink tubing of this type is typically rated for low-voltage applications up to 600V. It is commonly used in automotive wiring, RC battery packs, consumer electronics, and low-voltage control wiring. For high-voltage or industrial electrical installations, please contact us to confirm the appropriate specification for your use case before ordering.
