Quadrios 26CA767 Heat Shrink Tubing Without Adhesive Black 1 mm to 0.5 mm 2:1 10 m

Electricians and electronics technicians reach for this Quadrios heat shrink tubing when they need reliable insulation and strain relief on thin wires and cable splices. The black polyolefin sleeve slides over a 1 mm connection, then shrinks down to 0.5 mm under heat, creating a tight, professional seal without any adhesive residue.

Why choose it

The 2:1 shrink ratio and wide temperature tolerance make this tubing suitable for demanding environments, from engine compartments to outdoor control panels. It resists UV, moisture, and common chemicals, protecting connections from corrosion and abrasion.

Ideal use cases

• Insulating solder joints and crimp connectors on thin wires
• Bundling small wire harnesses in electronics projects
• Providing strain relief at connector backshells
• Repairing damaged insulation on sensor or signal cables

Good to know

This tubing is supplied as a continuous 10 m length, so you can cut it to the exact size needed for each joint. It does not contain adhesive, making it easy to remove if rework is required. Use a heat gun set to at least 70°C for controlled shrinkage; full recovery occurs at 110°C.
