Black 3mm Heat Shrink 3:1 | 15 cm x 8 Pcs

This flexible black heat shrink tubing offers a reliable solution for insulating and protecting electrical connections in a wide range of applications. Supplied as eight convenient 15 cm lengths, it is ideal for use in audio component assembly, electronics repair, and DIY wiring projects where secure, durable coverage is essential. The 3:1 shrink ratio ensures a tight, conforming fit over components with varying diameters, making it particularly useful for covering solder joints, connectors, and cable splices in tight spaces.

Technically, the tubing is manufactured from a high-quality polyolefin material that provides excellent electrical insulation and mechanical protection. When heated, it shrinks to one third of its original diameter, creating a snug, seamless barrier against moisture, dust, and abrasion. The black colour offers a professional finish, while the material’s flexibility allows it to follow contours without cracking. With a working temperature range suitable for most electronic environments, this heat shrink is a practical addition to any toolkit. Whether you are building custom audio cables or repairing circuit boards, these pre-cut lengths deliver consistent, hassle-free performance every time.
