CellPack 144430 Heat Shrink Tubing Without Adhesive Brown 3.2 mm 2:1 15 m

Electricians and maintenance technicians use this brown heat shrink tubing to insulate and protect wire splices in low-voltage installations. The 15-metre reel provides ample material for multiple repair jobs in control cabinets or automotive harnesses.

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.
