Heat Shrink Tubing – Multi-Color, 0.6mm to 70mm, 2:1 Ratio Electrical Sleeving
Heat Shrink Tubing for Every Wire, Cable & Connection — Reliable Insulation in 36 Sizes Whether you're repairing frayed wires under a dashboard, organizing cables in a server rack, or protecting solder joints on an RC build, finding the right heat shrink tubing in the exact size and color you need shouldn't be a hassle. This heat shrink tubing range is designed for hobbyists, electricians, automotive technicians, and DIYers who need a dependable, versatile sleeving solution without ordering from multiple suppliers. Each listing is sold per 1-meter length and is available in 36 diameters ranging from Ø0.6mm (≈0.024") to Ø70mm (≈2.76"), with a standard 2:1 shrink ratio. The tubing is made from polyolefin, a flexible, flame-retardant material that provides solid electrical insulation across a broad temperature range. Colors available include Black, White, Red, Green, Yellow, Blue, and Transparent — making color-coding and identification straightforward. Typical use cases include automotive wire harness repair, marine cable protection, RC car and drone wiring, home electrical projects, and workshop tool cord management. The wide size range makes this heat shrink tubing suitable for everything from delicate sensor wires to large-gauge power cables. ℹ️ Compatibility Note: This tubing uses a 2:1 shrink ratio. Select a pre-shrink diameter that is slightly larger than your wire or connector's outer diameter. For example, Ø6mm tubing shrinks to approximately 3mm (≈1/8"). Available in 1-meter lengths per order. ✅ Key Features of These Heat Shrink Tubing Sleeves 📐36 Diameter Options — Sizes from Ø0.6mm to Ø70mm cover fine signal wires, standard AWG cables, and large power conductors in a single product line. 🎨7 Color Choices — Black, White, Red, Green, Yellow, Blue, and Transparent allow easy color-coding for wire identification in automotive, marine, and electrical wiring projects. 🔥2:1 Shrink Ratio — Consistent shrinkage to half the original diameter when heated, creating a snug, secure fit around wires, connectors, and solder joints. ⚡Polyolefin Construction — Flame-retardant, flexible polyolefin material provides electrical insulation and moisture resistance suitable for indoor wiring and light outdoor cable protection. 🔧Easy to Apply — Shrinks uniformly with a standard heat gun; no adhesives or special tools required. Works for RC wiring, automotive harness repair, and workshop cable management. 📦Sold by the Meter — Order exactly the length you need in 1-meter increments, reducing waste and keeping your parts inventory lean. 📐 Technical Specifications — Heat Shrink Tubing Material Polyolefin (flame-retardant) Shrink Ratio 2:1 Diameter Range (Pre-Shrink) Ø0.6mm (≈0.024") – Ø70mm (≈2.76") Available Colors Black, White, Red, Green, Yellow, Blue, Transparent Packing Quantity 1 meter per order Voltage Rating Typically up to 600V (see variant options) Activation Temperature Typically 90–120°C (194–248°F) Operating Temperature Range Generally -55°C to +125°C (contact us to confirm) Flexibility Flexible after shrinking; suitable for moving cable assemblies Application Wire insulation, cable repair, solder joint protection, color-coding ⚠️ Size Tip: Always measure your wire or connector's outer diameter before selecting a size. The tubing should slide over the component easily before shrinking. When in doubt, size up — you can always apply more heat for a tighter fit. ❓ Frequently Asked Questions How do I choose the right diameter of heat shrink tubing? Measure the outer diameter of the wire or connector you need to cover, then choose a tubing size that is slightly larger before shrinking. With a 2:1 shrink ratio, the tubing will shrink to approximately half its listed diameter. For example, Ø6mm tubing will shrink down to roughly 3mm (≈1/8"). If you're covering a connector or splice, measure the widest point and size up accordingly. What shrink ratio does this tubing use? This heat shrink tubing generally uses a 2:1 shrink ratio, meaning it shrinks to approximately half its original diameter when heat is applied. This is the most common ratio for general-purpose electrical insulation and cable management applications. What temperature is needed to shrink the tubing? Typically, a heat gun set to around 90–120°C (194–248°F) is sufficient to activate the shrink. Move the heat gun slowly and evenly along the tubing to avoid hot spots. Avoid open flames as they can damage the tubing or the underlying wires. Can this tubing be used outdoors or in wet environments? Standard polyolefin heat shrink tubing generally provides moisture resistance suitable for most indoor and light outdoor applications. For fully waterproof sealing (such as marine or underground use), adhesive-lined (3:1) variants are typically recommended. Contact us to confirm suitability for your specific environment. What voltage rating does this heat shrink tubing support? Polyolefin heat shrink tubing of this type typically supports up to 600V, making it suitable for most low-voltage automotive, marine, and household electrical wiring. For high-voltage or industrial applications, please contact us to confirm the exact rating for your chosen size. Is this tubing compatible with standard wire gauges like AWG or metric? Yes. The metric diameter sizes (Ø0.6mm–Ø70mm) cover a wide range of wire gauges from very fine signal wires up to large power cables. Match the pre-shrink diameter to your wire's outer diameter for a snug fit after shrinking. If you're unsure, our size range typically covers AWG 30 through 4/0 and beyond. Can I use a lighter or hair dryer instead of a heat gun? A hair dryer may work for smaller diameters (Ø0.6mm–Ø3mm) but generally does not produce enough consistent heat for larger sizes. A heat gun is recommended for even, reliable shrinking across all sizes. Open flames are not recommended as they can scorch the tubing and damage the wire insulation underneath. 🛒 Select your diameter and color above, then add to cart — ships from our US warehouse.
