PVC Heat Shrink Tubing — Color-Coded Wire Sleeving in 23mm, 27mm & 29.5mm Flattened Width

Whether you're rewiring a car stereo, tidying up a home electrical panel, or finishing off a DIY electronics build, mismatched or unlabeled wires are a constant headache. PVC heat shrink tubing lets you insulate, protect, and color-code your cables in one step — giving hobbyists, auto technicians, and electricians a clean, professional result every time.

Each piece is made from flexible PVC material with a 2:1 shrink ratio. Available in three flattened widths — 23mm (≈ 0.91"), 27mm (≈ 1.06"), and 29.5mm (≈ 1.16") — and sold in packs of 1, 5, 10, or 20 pieces. With 28 color options ranging from classic Black and White to Transparent Gold, Sky Blue, and Dark-red, you have everything you need to build a consistent color-coding system across your project.

Typical use cases include automotive wiring harness repair, home electrical wire bundling, marine cable protection in sheltered environments, and electronics prototyping where quick visual identification of circuits saves time and prevents mistakes.

🔌 Compatibility: Fits standard round cables and wire bundles. Expanded inner diameter is approximately 14.6mm for 23mm width, 17mm for 27mm, and 18.8mm for 29.5mm. Verify your cable's outer diameter before selecting a size.
⚠️ Please confirm: Cut length per piece may vary by color batch. If you require a specific length, contact us before ordering to confirm.

✅ Key Features of These PVC Heat Shrink Tubing Sleeves

  • 🎨28 Color Options — From solid Black, White, and Red to specialty shades like Transparent Gold, Lake Blue, and Tangerine, making color-coded wire identification straightforward on any project.
  • 📐Three Flattened Widths — 23mm (≈ 0.91"), 27mm (≈ 1.06"), and 29.5mm (≈ 1.16") cover a wide range of cable outer diameters, from small gauge wires to larger bundled harnesses.
  • 🔥2:1 Shrink Ratio — Shrinks to approximately half its expanded diameter when heated to around 70–90°C (158–194°F), creating a snug, uniform fit around the cable without gaps.
  • 🛡️Electrical Insulation — PVC construction provides a reliable insulating layer over wire splices, terminals, and connectors, reducing the risk of short circuits in automotive and DIY electrical work.
  • 📦Flexible Pack Sizes — Order 1, 5, 10, or 20 pieces per color to match your project scale, whether you need a single repair piece or a bulk supply for a full wiring harness job.
  • ✂️Easy to Cut and Apply — PVC tubing cuts cleanly with standard scissors or a utility knife, and shrinks evenly with a heat gun, making it accessible for both first-time DIYers and experienced technicians.

❓ Frequently Asked Questions

How do I choose the right flattened width for my wire or cable?

The flattened width is roughly half the expanded inner diameter of the tubing. As a general rule, choose a tube whose expanded diameter is at least 20% larger than your cable's outer diameter. For example, the 23mm flattened width (≈ 0.91" / ~14.6mm expanded) typically suits cables up to about 12mm OD; 27mm (≈ 1.06" / ~17mm expanded) suits up to ~14mm OD; and 29.5mm (≈ 1.16" / ~18.8mm expanded) suits up to ~16mm OD. When in doubt, size up.

What shrink ratio does this PVC tubing have, and how much will it shrink?

This tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its expanded diameter when heat is applied. For example, a 27mm flattened width tube with ~17mm expanded inner diameter will shrink down to roughly 8–9mm inner diameter after heating — suitable for snugly covering cables in that range.

What temperature do I need to shrink this tubing, and can I use a heat gun?

PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). A standard heat gun set to low or medium heat works well. Move the heat gun slowly and evenly along the tubing to avoid scorching. Avoid open flames, as they can cause uneven shrinkage or damage the material.

Can this tubing be used outdoors or in wet environments?

PVC heat shrink tubing provides basic moisture resistance and is generally suitable for light indoor and sheltered outdoor use. For prolonged outdoor exposure, UV resistance, or submersion applications, a polyolefin or adhesive-lined heat shrink tubing is typically recommended instead. If you're unsure, contact us to confirm suitability for your specific environment.

Is this tubing compatible with standard automotive and household wire gauges?

Yes. The three available flattened widths — 23mm, 27mm, and 29.5mm — are compatible with a broad range of wire gauges and cable bundles commonly used in automotive wiring harness repair, home electrical projects, and electronics work. Always verify the expanded inner diameter against your cable's outer diameter before ordering to ensure a proper fit.

Why should I use color-coded heat shrink tubing instead of plain black?

Color coding makes it easy to identify circuits, polarity, or wire functions at a glance — a practice widely used in automotive wiring, home electrical projects, and electronics repair. With 28 color options available, you can establish a consistent color system across your entire project, reducing the chance of wiring errors during installation or future maintenance.

How much tubing do I get per pack, and what is the length of each piece?

Each listing offers packs of 1, 5, 10, or 20 pieces. The length per piece may vary by color batch. If you need a specific cut length for your project, please contact us before ordering to confirm the available length for your chosen color and width.
