Green PVC Heat Shrink Tubing — RC Battery Pack, LED & Wire Wrap | 12mm–333mm Flat Width

Measure the outer diameter of the object you want to cover, then divide by 0.637 to get the minimum flat width needed. For example, a 10mm diameter object typically requires at least a 16mm flat width tube. When in doubt, size up — PVC heat shrink generally shrinks to about 50% of its flat width diameter. Each variant lists both the flat width and the recovered inner diameter (e.g., 12mm flat → Ø7.6mm recovered) to help you match precisely.

This tubing has a 2:1 shrink ratio, meaning it shrinks to approximately half its original expanded diameter when heat is applied. The recovered (inner) diameter is listed alongside each flat width in the variant options, so you can confirm the final fit before purchasing.

PVC heat shrink tubing generally activates at 70°C–90°C (158°F–194°F). A heat gun on a low setting, a hair dryer, or even hot water can typically be used for smaller sizes. Move the heat source evenly along the tubing to avoid scorching. Avoid open flames, which can cause uneven shrinkage or damage the material.

Standard single-wall PVC heat shrink tubing provides basic moisture resistance and is generally suitable for light indoor and outdoor use. However, it does not have an adhesive inner lining and is not designed for full submersion or high-humidity environments. For waterproof sealing applications, dual-wall adhesive-lined heat shrink tubing is typically recommended.

Yes — this is one of the most common uses for this type of tubing. The green color aids in pack identification, and the wide flat-width range (12mm–333mm) accommodates most standard RC battery form factors. To size correctly, measure the perimeter of your battery pack and divide by π (≈3.14) to get the approximate diameter, then select the flat width accordingly.

For a single battery pack wrap or a few connector joints, 1m is generally sufficient. For workshop or small-batch production use, 5m–20m rolls offer a good balance of value and storage. For high-volume production or resale, 50m–200m bulk rolls provide the best per-meter pricing. All lengths are cut from the same continuous roll.

PVC heat shrink tubing of this type is typically rated for up to 600V and an operating temperature range of -20°C to 105°C (-4°F to 221°F).
