Quadrios 26CA778 zmršťovacia bužírka, bez lepidla, čierna, 25 mm až 12,5 mm, 2:1, 5 m

Electricians and maintenance technicians rely on this heat shrink tubing to insulate and protect cable splices, terminations, and repairs in industrial and automotive environments. The 25 mm unshrunk diameter slides easily over connectors and bulky wire bundles, then recovers to 12.5 mm for a tight, professional finish.

Why choose it

This tubing offers reliable electrical insulation and mechanical protection without adhesive, making it easy to reposition before heating. The polyolefin material is flame retardant and withstands a wide temperature range, suitable for demanding environments.

Ideal use cases

• Insulating electrical splices and terminations
• Bundling and protecting wire harnesses
• Repairing damaged cable jackets
• Providing strain relief at connector backshells

Good to know

The tubing is RoHS compliant and offers good resistance to chemicals and UV exposure. For best results, use a heat gun and apply heat evenly until the tubing fully recovers and conforms to the substrate.
