Quadrios 26CA769 Heat Shrink Tubing 4 mm to 2 mm, 2:1, Black, 10 m

Electricians and electronics technicians often need a reliable way to insulate wire splices, bundle cables, or provide strain relief in tight spaces. The Quadrios 26CA769 heat shrink tubing offers a simple solution: slide it over the area, apply heat, and it shrinks to form a tight, protective seal. This black polyolefin tubing has a 2:1 shrink ratio, reducing from an initial inner diameter of 4 mm to a fully shrunk diameter of 2 mm. Supplied on a 10-meter spool, it is ready for use in workshops, on production lines, or in field repairs.

Why choose it

This tubing is made from cross-linked polyolefin, which provides good electrical insulation and resistance to common chemicals and abrasion. It is not adhesive lined, so it is easy to slide over wires before shrinking. The 2:1 ratio means it can accommodate slight variations in diameter while still achieving a snug fit.

Ideal use cases

• Insulating electrical splices and terminations
• Bundling wires and cables for neatness
• Providing strain relief at connectors
• Protecting components from dust and moisture

Good to know

The tubing meets UL224 VW-1 flammability standards and is suitable for use in a wide range of temperatures. It is commonly used in automotive, marine, and general electrical applications.
