Wire Heat Shrink Tubing Assortment Set 164 Piece

Organise, insulate and protect your wiring with confidence.

This 164-piece Wire Heat Shrink Tubing Set provides a versatile range of sizes and colours for reliable electrical insulation, repair and identification. Manufactured from durable polyolefin with a 2:1 shrink ratio, each tube contracts uniformly when heated to create a secure, long-lasting seal around cables, leads and connectors. The material offers robust tensile strength and excellent dielectric properties, supporting safe use across a wide range of low-voltage applications.

Ideal for repairing damaged insulation, bundling cables or colour-coding circuits, these heat shrink tubes are simple to use and deliver a neat, professional finish. Just slide the appropriate size tubing over the exposed or joined section of wire, then apply hot air using a heat gun or similar device. As the tubing shrinks, it conforms tightly to the cable, helping to protect against abrasion, moisture and accidental contact. Suitable for automotive, DIY, electronics, and workshop use, this set is designed to support clean, organised and clearly identified wiring.

Why It's a Smart Choice

• Comprehensive size range - Includes 164 pieces from 1.0 mm to 14.0 mm diameters to cover common household, automotive and hobby wiring tasks.
• Durable polyolefin construction - 2:1 shrink ratio with good tensile strength and dielectric performance for consistent insulation and strain relief.
• Colour-coded organisation - Multiple colours (yellow, black, red, green, blue) make it easy to identify circuits and simplify troubleshooting.

FAQ

Q: What tools do I need to shrink the tubing?
A: A heat gun is recommended for best results. A high-heat hair dryer may work on smaller sizes, but a dedicated heat gun provides more consistent shrinking.

Q: What is the operating temperature range?
A: The tubing is designed for an operating temperature range of approximately -55°C to +125°C, suitable for most indoor and many automotive environments.

Q: Can this be used outdoors?
A: Yes, once correctly shrunk, the tubing forms a snug, protective layer that helps resist moisture and abrasion. For long-term outdoor or harsh-environment use, ensure proper sealing at cable ends and follow relevant electrical standards.

Q: Is it suitable for data and electronics wiring?
A: Yes, it can be used on low-voltage signal, audio, and electronics wiring to insulate solder joints, reinforce connectors and provide strain relief.
