Quadrios 26CA776 Heat Shrink Tubing, 2:1, 18 mm to 9 mm, Black, 5 m, Halogen-Free Polyolefin

Electricians and maintenance technicians often need to insulate and protect wire splices, cable joints, and connectors in industrial control panels or automotive harnesses. This Quadrios 26CA776 heat shrink tubing provides a reliable solution: a 5-meter length of black polyolefin tubing that shrinks from 18 mm down to 9 mm when heated, at a 2:1 ratio. It is non-adhesive, halogen-free, and rated for 600 V, making it suitable for a wide range of electrical insulation tasks.

Why choose it

The 2:1 shrink ratio ensures a tight, secure fit over irregular shapes. The halogen-free polyolefin material is safer for environments where toxic fumes are a concern. With a wide operating temperature range, it performs reliably in both cold and hot conditions.

Ideal use cases

• Insulating electrical splices and terminations
• Bundling wires for neat cable management
• Protecting cables from abrasion and moisture
• Repairing damaged insulation in automotive or marine wiring

Good to know

This tubing does not have an adhesive lining, so it is not intended for waterproof sealing. It is supplied in a continuous 5-meter length, allowing you to cut it to the exact size needed for each job.
