Color-Coded Heat Shrink Tubing — Protect, Insulate & Identify Wires in One Step

Loose wire splices, exposed solder joints, and tangled cable bundles are a headache for any DIYer, auto electrician, or electronics hobbyist. One wrong connection can mean a short circuit, a failed repair, or hours of troubleshooting. These colored heat shrink tubes let you seal and protect every connection cleanly while using color to keep your wiring organized at a glance.

Each piece is made from flexible polyolefin material with a typically 2:1 shrink ratio. Available in six diameters — φ3mm (≈0.12"), φ3.5mm (≈0.14"), φ4mm (≈0.16"), φ4.5mm (≈0.18"), φ5mm (≈0.20"), and φ5.5mm (≈0.22") — and seven colors: Black, White, Red, Green, Yellow, Blue, and Transparent. Choose from packs of 1, 5, 10, or 20 pieces to match your project scale.

Ideal for automotive wiring harness repair, home electrical DIY projects, RC hobby electronics, marine cable protection, and color-coding multi-wire control panels. Whether you're insulating a car stereo splice, protecting a soldered LED connection, or tidying up a home workshop cable run, these heat shrink sleeves deliver a clean, professional finish every time.

🔌 Compatible with: Copper wire, stranded cable, solid-core wire, solder joints, terminal connectors, and butt splices. Suitable for automotive, marine, household, and low-voltage electronics applications.

✅ Key Features of These Colored Heat Shrink Tubes

  • 🎨 7-Color Identification System — Black, White, Red, Green, Yellow, Blue, and Transparent options make it easy to color-code wiring circuits, reducing troubleshooting time in complex harnesses.
  • 📐 6 Precise Diameter Sizes — From φ3mm to φ5.5mm in 0.5mm increments, giving you a snug fit on a wide range of wire gauges typically from AWG 28 down to AWG 10.
  • 🔥 Low Activation Temperature — Shrinks reliably with a standard heat gun, lighter, or even a hair dryer at generally 90–120°C (194–248°F), making it accessible for field repairs without specialist tools.
  • 🛡️ Electrical Insulation & Moisture Resistance — Once shrunk, the tubing forms a tight sleeve that insulates exposed conductors and provides basic protection against moisture, dust, and abrasion.
  • ✂️ Cut-to-Length Flexibility — Each tube can be trimmed to any length before shrinking, so there's no waste and you get a perfectly sized sleeve for every connector or splice.
  • 📦 Flexible Pack Sizes for Every Need — Order 1 piece for a quick single repair, or choose 5, 10, or 20-piece packs for workshop stock, automotive projects, or bulk DIY jobs — with per-unit savings on larger quantities.

❓ Frequently Asked Questions

What shrink ratio does this heat shrink tubing have?

This tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original diameter when heat is applied. Please confirm the exact ratio for your chosen size variant before use in precision applications.

What temperature is needed to shrink the tubing?

Typically, a heat gun set to around 90–120°C (194–248°F) is sufficient. A lighter or hair dryer can also work for smaller diameters, though a heat gun gives the most even, controlled results.

Is this tubing suitable for automotive wiring?

Yes. These tubes are commonly used for car audio wiring, trailer harnesses, and general automotive cable protection. The color options also help with wire identification in vehicle electrical systems.

Can I use this for outdoor or waterproof applications?

Standard polyolefin heat shrink tubing provides basic moisture resistance once shrunk. For fully waterproof applications, we recommend using adhesive-lined (dual-wall) heat shrink tubing instead. Contact us to confirm suitability for your specific environment.

How do I choose the right diameter?

Select a diameter that is slightly larger than the cable or connector you need to cover. For example, for a 2mm wire, φ3mm tubing is a good starting point. After shrinking, it will grip the wire snugly. When in doubt, size up — you can always shrink tighter, but you can't stretch the tube back.

What is the wall thickness of the tubing?

Wall thickness varies by diameter. Please see the variant options or contact us to confirm the exact wall thickness for your selected size before ordering for critical insulation applications.

Can I cut the tubing to a custom length?

Yes. The tubing can be cut to any length with scissors or a utility knife before applying heat. Each piece in the pack is typically supplied as a standard-length segment, giving you flexibility to trim as needed.
