Heat-Shrink Sleeves Silver set, 127 pcs, black — Silver 11371

Set of 127 black heat-shrink sleeves from Silver designed to insulate and protect electrical wire joints and cable ends. The kit contains a selection of sleeve diameters and lengths to cover common wiring needs in household, workshop and light commercial applications. Heat-shrink sleeves provide a tight, protective coating after heat is applied, improving mechanical durability and electrical insulation of splices, terminations and repairs.

Advantages

These heat-shrink sleeves offer consistent shrink performance and reliable insulation for low-voltage electrical connections. The black sleeves are made for general-purpose use, providing abrasion resistance and protection against moisture ingress in typical indoor and sheltered outdoor environments. The compact set of multiple sizes streamlines repairs and reduces the need to cut or re-measure tubing for each job.

Suitable for

• Insulating spliced wires in household electrical repairs
• Protecting cable ends and solder joints in electronics and audio installations
• Securing automotive low-voltage wiring and small harness repairs
• Workshop and DIY projects requiring heat-activated tubing

Key specifications

• Color: black
• Quantity: 127 pieces
• Material type: heat-shrink polyolefin (typical for electrical sleeves)
• Function: provides electrical insulation and mechanical protection after heat shrinking
• Application range: suitable for low-voltage wiring, splices, and terminations

How to use

Slide an appropriately sized sleeve over the wire or splice before making the electrical connection. After soldering or crimping the joint, position the sleeve to fully cover the exposed area and apply heat evenly using a heat gun or appropriate heat source until the sleeve shrinks and conforms to the cable. Allow the sleeve to cool to form a secure insulating layer. For best results, choose a sleeve diameter slightly larger than the unshrunk cable and ensure the heat source is moved continuously to avoid overheating one spot.

Usage recommendations

Use a temperature-controlled heat gun when available and follow standard electrical safety practices. Avoid open flames and excessive heat that can damage conductors or insulation. Store the sleeves in a dry place away from direct sunlight to maintain material properties.
