Black 3mm Heat Shrink 3:1 w/Adhesive | 15 cm x 8 Pcs.

This Black 3mm Heat Shrink tubing with a 3:1 shrink ratio and integrated adhesive lining offers a robust solution for sealing and insulating electrical connections. Supplied as eight pieces, each 15 centimetres in length, this pack provides ample material for a variety of small-scale wiring projects, ensuring durable, long-lasting protection against moisture and environmental contaminants.

Ideal for use in automotive repairs, marine electronics, or household wiring tasks, this heat shrink tube excels where reliable waterproofing is essential. The adhesive inner layer melts upon heating, creating a secure, airtight bond around cables, terminals, or connectors. This makes it particularly suitable for outdoor lighting, sensor installations, or any application exposed to damp conditions, where standard tubing might fail.

The 3:1 shrink ratio allows the tubing to reduce to one-third of its original diameter, accommodating components with varying thicknesses while ensuring a tight fit. The black colour provides a professional finish, and the adhesive lining not only seals against moisture but also adds mechanical strain relief. Simply slide the tube over the connection, apply heat with a heat gun or lighter, and watch it conform precisely.

For dependable insulation and waterproof sealing in a compact, easy-to-use format, this adhesive-lined heat shrink tubing delivers consistent performance across numerous electrical tasks.
