BKL Electronic 074114 Heat Shrink Tubing, Black, 1.6 mm / 0.8 mm, 2:1, 200 m Roll

Electricians and electronics technicians rely on this black heat shrink tubing to insulate and protect wire splices in control cabinets and automotive harnesses. The 2:1 shrink ratio means the tubing recovers to half its supplied diameter when heated, gripping the underlying conductors tightly.

Why choose it

The thin wall construction adds minimal bulk while providing reliable electrical insulation and strain relief. The polyolefin material is flexible and resists common solvents, oils, and UV exposure, making it suitable for both indoor and outdoor use.

Ideal use cases

• Insulating soldered or crimped connections
• Bundling small wire groups
• Providing abrasion protection in tight spaces
• Colour-coding conductors in black

Good to know

The tubing is supplied on a 200 m roll for convenient dispensing. It meets UL 224 VW-1 and CSA C22.2 No. 198.1 standards for flame retardancy.
