1.5mm Heat Shrink Tubing — Reliable Insulation for Automotive & Electrical Wire Repairs

Whether you're chasing an electrical gremlin in your car, tidying up a home wiring project, or building a custom wiring harness from scratch, loose or exposed wire ends are a safety hazard and a headache. This 1.5mm heat shrink tubing gives hobbyists, automotive enthusiasts, and electricians a clean, durable way to insulate, protect, and organize wire connections of all kinds.

Each order is a continuous length of polyolefin heat shrink tubing with a 2:1 shrink ratio and a pre-shrink inner diameter of φ1.5mm (≈1/16"). Available in four lengths — 1m (≈3.3ft), 2m (≈6.6ft), 5m (≈16.4ft), and 10m (≈32.8ft) — and seven colors: Black, White, Red, Green, Yellow, Blue, and Transparent. The 2:1 ratio means the tubing recovers to approximately 0.75mm inner diameter when heat is applied, forming a tight, uniform sleeve around the wire.

This tubing is well suited for insulating soldered wire splices in automotive electrical systems, color-coding wiring harnesses for easy circuit identification, protecting small-gauge wire ends on marine electronics, and bundling delicate leads on hobby electronics and RC builds where a clean, professional finish matters.

🔌 Compatibility: Designed for 26–22 AWG wire (typically 0.4–0.6mm conductor diameter). Verify your wire's outer insulation diameter is under 1.5mm before ordering. For larger wire gauges, see our full heat shrink tubing range.

✅ Key Features of These 1.5mm Heat Shrink Tubes

  • 🔥2:1 Shrink Ratio — Recovers to approximately half its original diameter, creating a snug, uniform sleeve that conforms tightly to wire insulation without gaps or loose ends.
  • 🎨7 Color Options — Black, White, Red, Green, Yellow, Blue, and Transparent allow color-coded wire identification — a standard practice in automotive wiring harness builds and panel wiring.
  • 📏Four Length Choices — Order exactly what your project needs: 1m for quick repairs, 2m for small jobs, 5m for wiring harness work, or 10m for bulk electrical cable insulation projects.
  • 🛡️Moisture & Abrasion Resistance — Polyolefin construction provides a protective barrier against moisture ingress, mild chemicals, and physical abrasion — useful in under-hood automotive and marine environments.
  • ⚡Low Activation Temperature — Begins shrinking at approximately 90°C (194°F), so a standard heat gun on low setting is all you need — no specialized tools required for most small-gauge wire wrap applications.
  • ✂️Easy to Cut & Position — Cuts cleanly with standard scissors or wire cutters, and slides freely over wire before shrinking, making it straightforward to position precisely over splices, terminals, or connector ends.

⚠️ Size tip: Always measure your wire's outer diameter (including insulation) before ordering. The pre-shrink ID of 1.5mm should be slightly larger than your wire for easy sliding, and the recovered ID of ~0.75mm should be smaller than your wire for a tight seal.

❓ Frequently Asked Questions

What does 1.5mm inner diameter mean, and will it fit my wire?

The 1.5mm (approximately 1/16") measurement refers to the inner diameter before shrinking. With a 2:1 shrink ratio, it recovers to roughly 0.75mm. This size is generally suited for 26–22 AWG wire or small-gauge conductors. If your wire diameter is close to 0.75mm after insulation, this tubing will typically provide a snug, secure fit.

How much heat does this tubing need to shrink?

Polyolefin heat shrink tubing generally activates at around 90°C (194°F) and fully recovers by 120°C (248°F). A heat gun set to low or medium is the recommended tool. A lighter can work in a pinch but may scorch the tubing — use it carefully and keep it moving.

Can I use this heat shrink tubing outdoors or in my car engine bay?

Polyolefin tubing is generally resistant to moisture, mild chemicals, and UV exposure, making it suitable for automotive and outdoor low-voltage wiring. For prolonged direct UV exposure or high-heat engine-bay environments, confirm the operating temperature range matches your application before installing.

What is the voltage rating for this tubing?

Standard polyolefin 2:1 heat shrink tubing is typically rated for up to 600V. This makes it suitable for most low-voltage automotive, marine, and household electrical wiring tasks. For high-voltage industrial applications, please contact us to confirm suitability.

How do I choose the right length for my project?

Measure the total length of wire or splice you need to cover, then add about 10–15% extra for overlap and trimming. For a single repair job, 1m or 2m is usually sufficient. For wiring harness builds or bulk automotive projects, the 5m or 10m options offer better value per meter.

Does the color affect performance, or is it purely cosmetic?

Color is primarily for identification and organization — all seven colors (Black, White, Red, Green, Yellow, Blue, Transparent) share the same 2:1 shrink ratio and material properties. Using color-coded tubing is a common practice in automotive and electrical work to quickly identify wire functions or circuits.

Can this tubing be used for wire splicing and connector insulation?

Yes. Heat shrink tubing is one of the most reliable methods for insulating soldered wire splices, butt connectors, and terminal ends. Slide the tubing over the wire before soldering, make your connection, then slide the tubing over the joint and apply heat to seal it.
