Why choose it

This tubing shrinks uniformly when heated, creating a tight, professional finish without adhesive residue. The brown colour blends with common wire insulation, and the polyolefin material resists common solvents and abrasion.

Ideal use cases

• Insulating soldered or crimped connections
• Bundling wires in automotive or marine applications
• Providing strain relief at connector backshells
• Colour-coding circuits for identification

Good to know

Apply heat evenly with a hot air gun until the tubing fully recovers. Avoid overheating to prevent charring. The tubing is self-extinguishing and meets UL VW-1 flammability requirements.
