1.7:1 Heat Shrink Tubing — Reliable Wire Insulation from φ0.8mm to φ40mm

Loose wire ends, exposed splices, and unlabeled cable bundles are a safety hazard and a troubleshooting nightmare. Whether you're a hobbyist finishing a DIY electronics project, an auto technician repairing a wiring harness, or a professional electrician organizing a panel, you need heat shrink tubing that fits precisely, shrinks cleanly, and stays put.

Each listing covers a single piece or roll of 1.7:1 polyolefin heat shrink tubing, available in diameters from φ0.8mm (≈1/32") to φ40mm (≈1-9/16"), in 1-meter (≈3.3 ft) or 10-meter (≈32.8 ft) lengths. Colors include Black, White, Iron Red, Pink, Blue, Yellow, and Grey — sold by size and color variant so you get exactly what you need.

Typical use cases include insulating soldered wire joints for home electrical repairs, color-coding automotive wiring harnesses to simplify diagnostics, bundling and protecting exposed cables in marine or RV installations, and adding strain relief to connector terminations in electronics prototyping.

ℹ️ Compatibility Note: This tubing is designed for standard round wires and cables. Measure your wire's outer diameter before ordering — the pre-shrink inner diameter should be at least 10–20% larger than the object being covered. After shrinking, the tubing reduces to approximately 59% of its original inner diameter.

✅ Key Features of These Heat Shrink Tubing Sleeves

  • 🔥1.7:1 Shrink Ratio — Shrinks to approximately 59% of its original diameter, providing a snug, conforming fit around wires, connectors, and cable bundles without excessive bulk.
  • 📏Wide Size Range — Available from φ0.8mm to φ40mm, covering everything from fine gauge signal wires to large-diameter power cables and conduit ends.
  • 🎨7 Color Options — Black, White, Iron Red, Pink, Blue, Yellow, and Grey allow color-coded wire identification for automotive, marine, and electrical panel wiring.
  • 🛡️Flame-Retardant Polyolefin — Made from polyolefin material that is generally flame-retardant and resistant to moisture, mild chemicals, and abrasion — suitable for indoor and outdoor cable protection.
  • ⚡Electrical Insulation — Provides a reliable dielectric barrier over solder joints, wire splices, and terminal connections, reducing the risk of short circuits and corrosion.
  • 📦Flexible Length Options — Choose 1-meter lengths for small repairs and prototyping, or 10-meter rolls for larger wiring projects and production runs where consistent coverage is needed.

Activation Temperature Typically ≥90°C (194°F)
Full Shrink Temperature Typically ≈120°C (248°F)
Operating Temperature Range Typically -55°C to +125°C (-67°F to +257°F)
Wall Thickness (Post-Shrink) See variant options
Flame Retardancy Generally flame-retardant (contact us to confirm specific rating)

⚠️ Sizing Tip: If you are between sizes, size up — it is easier to shrink a slightly larger tube than to force a too-small one over a connector. For connectors with flanges or irregular shapes, choose a diameter that clears the widest point.

❓ Frequently Asked Questions

How do I choose the right diameter for my wire?

Measure your wire or connector's outer diameter before shrinking. The tubing's pre-shrink inner diameter should be larger than the object — typically 1.2–1.5× the object's diameter. For example, a 3mm wire generally works well with φ4mm or φ5mm tubing. After heat is applied, the tube shrinks to approximately 59% of its original diameter.

What shrink ratio does this tubing use?

This tubing has a 1.7:1 shrink ratio, meaning it shrinks to approximately 59% of its original inner diameter when heat is applied. This ratio is generally suitable for standard wire bundling, insulation, and strain relief applications.

What temperature is needed to shrink this tubing?

Polyolefin heat shrink tubing typically activates at around 90°C (194°F) and fully shrinks at approximately 120°C (248°F). A heat gun is recommended for even, controlled shrinkage. A lighter can work in a pinch but may cause uneven results or scorching on larger diameters.

Is this tubing flame-retardant and safe for outdoor use?

Polyolefin heat shrink tubing is generally flame-retardant and provides good resistance to moisture, mild chemicals, and UV exposure, making it suitable for many outdoor and automotive applications. For prolonged outdoor or harsh-environment use, please contact us to confirm the specific rating for your application.

Can I use this tubing for automotive or marine wiring?

Yes, polyolefin heat shrink tubing is commonly used in automotive, marine, and RV wiring for insulation, color-coding, and strain relief. It typically withstands temperatures from -55°C to +125°C (-67°F to +257°F), making it suitable for engine bays and exposed wiring runs in most vehicles and watercraft.

What is the difference between the 1-meter and 10-meter options?

The 1-meter option is ideal for small repairs, prototyping, or when you only need a short run. The 10-meter roll is more economical for larger projects, production runs, or when you need consistent color-coding across multiple wires. Both options are available in the same diameter and color selections.

How do I choose between the available colors?

Color selection is typically used for wire identification and circuit organization. Common conventions include black for ground, red or iron red for positive/power, blue for signal lines, yellow for caution circuits, and white for neutral. Grey is popular for industrial or custom labeling. Pink is often used in consumer electronics and decorative wiring projects.

Can this tubing be used on connectors and terminals, not just bare wire?

Yes, heat shrink tubing is commonly applied over solder joints, crimp terminals, butt connectors, and ring terminals to provide insulation and strain relief. Choose a diameter that fits over the widest part of the connector. In most cases, sizing up one step from the wire diameter is sufficient to clear standard terminal bodies.
