PVC Heat Shrink Tubing — Large-Diameter Colored Sleeving for Wire, Cable & DIY Projects

When you're bundling thick cables, insulating large wire terminations, or adding color-coded identification to a wiring harness, standard small-bore tubing just doesn't cut it. This PVC heat shrink tubing is designed for applications that demand wider coverage — available in flattened widths from 50mm (≈2") to 78mm (≈3"), it handles the jobs that smaller sleeves can't reach.

Each piece is made from flexible PVC with a typical 2:1 shrink ratio. The tubing is sold by flattened width — the measurement when the tube is laid flat — in seven sizes: 50mm (≈2"), 55mm (≈2.2"), 60mm (≈2.4"), 66mm (≈2.6"), 70mm (≈2.8"), 75mm (≈3"), and 78mm (≈3.1"). Choose from 13 colors including Black, White, Red, Blue, Yellow, Green, Transparent, and more. Available in packs of 1, 5, 10, or 20 pieces.

Typical use cases include insulating large wire splices and battery terminals, color-coding cable bundles in automotive wiring, protecting copper pipe joints, bundling garden hose connections, and organizing thick multi-conductor cables in panel builds — all scenarios where colored heat shrink wrap sleeving in larger diameters is hard to find locally.

ℹ️ Sizing note: The width listed is the flattened (lay-flat) width, not the diameter. To estimate pre-shrink inner diameter, divide the flat width by π (≈3.14). Select a size that fits loosely over your cable before applying heat. See FAQ below for examples.

✅ Key Features of These PVC Heat Shrink Tubing Sleeves

  • 📏Wide Size Range — Seven flattened widths from 50mm to 78mm cover large-diameter cables, pipe joints, and bundled wire harnesses that standard small-bore tubing cannot accommodate.
  • 🎨13 Color Options — Black, White, Red, Blue, Yellow, Green, Transparent, Fruit Green, Silver Grey, Purple, Red-Orange, Orange, and Light Yellow make color-coding and circuit identification straightforward on any job.
  • 🔥Consistent Heat Activation — PVC material shrinks evenly when a heat gun is applied at typically 70–120°C (158–248°F), conforming snugly around irregular shapes without cracking or splitting.
  • ⚡Electrical Insulation — Provides a protective insulating layer over wire splices, terminals, and connectors, reducing the risk of short circuits in residential wiring and light commercial panel work.
  • ✂️Cut-to-Length Flexibility — Each piece can be cut to any length before shrinking, giving you precise coverage without waste — useful for both short repair patches and longer cable runs.
  • 📦Bulk Pack Options — Order 1, 5, 10, or 20 pieces per color and size. Stocking multiple colors in the 10 or 20 Pcs packs keeps your workshop ready for any large-diameter heat shrink wrap sleeving job.

❓ Frequently Asked Questions

How do I choose the right flattened width for my application?

The flattened width listed (e.g., 50mm) is the width when the tubing is laid flat. The pre-shrink inner diameter is approximately flat width ÷ π (3.14). For example, a 50mm flat-width tube has a pre-shrink diameter of roughly 15.9mm (≈5/8"). Choose a size that fits loosely over your cable or object before applying heat — typically 10–20% larger than the object's diameter. After shrinking, the tube will conform snugly around it.

What is the shrink ratio, and how much will the tubing shrink?

PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original inner diameter when heat is applied. So a tube with a 15mm pre-shrink diameter will typically recover to around 7–8mm. The exact ratio may vary slightly by size — contact us if you need precise specifications for a critical application.

What temperature do I need to shrink this tubing, and what tool should I use?

PVC heat shrink tubing typically activates between 70°C and 120°C (158°F–248°F). A heat gun on a low or medium setting is the recommended tool — move it steadily along the tubing to shrink evenly. Avoid using open flames (lighters, torches), which can scorch or melt the PVC unevenly and create weak spots.

Can I use this tubing outdoors or in wet conditions?

Standard PVC heat shrink tubing offers basic moisture resistance and is generally suitable for indoor use and light outdoor applications where it won't be submerged or exposed to prolonged UV radiation. For harsh outdoor environments, direct sunlight exposure, or underwater use, we recommend confirming suitability with us before ordering, or considering adhesive-lined heat shrink alternatives.

Is this compatible with standard electrical wire and cable insulation?

Yes. This PVC heat shrink tubing is compatible with copper wire, aluminum wire, and most standard cable jacket materials. It is commonly used for electrical insulation over wire splices, terminal connections, and multi-conductor bundles in residential wiring, automotive applications, and light commercial panel work. Always verify the voltage rating meets your application requirements.

How do I convert the flattened width to inches?

Divide the millimeter value by 25.4 to convert to inches. Quick reference for this product's sizes:

  • 50mm ≈ 2.0"
  • 55mm ≈ 2.2"
  • 60mm ≈ 2.4"
  • 66mm ≈ 2.6"
  • 70mm ≈ 2.8"
  • 75mm ≈ 3.0"
  • 78mm ≈ 3.1"

These are the flattened widths. Pre-shrink inner diameter ≈ flat width ÷ π (3.14).

Which pack size is right for me?

The 1 Pcs option is ideal for single repairs, prototyping, or trying a new size. The 5 Pcs pack suits small projects or occasional use. The 10 Pcs pack is a good workshop stock level for recurring jobs. The 20 Pcs pack offers the best per-piece value for contractors, production runs, or anyone who regularly works with large-diameter heat shrink wrap sleeving.
