## Summary description

The kit provides assorted sizes of thermally responsive polyolefin sleeves suitable for insulating joins, strain relief, and color-coding wires in electronics, automotive and household wiring.

## Long description

Isma heat shrink tubing set contains 128 pieces of polyolefin sleeves in assorted diameters and lengths designed for electrical insulation, cable protection and wire identification. The kit includes a small cutter for accurate trimming and fast preparation. Tubing in the set is thermally responsive: when heated it contracts to provide secure insulation and strain relief around soldered joints, connectors and exposed conductors in electronics, automotive and household wiring.
Advantages
The set offers a wide range of sizes to cover common wire diameters and joint types, enabling neat and reliable insulation without the need to buy multiple separate tubes. Polyolefin material provides electrical insulation properties and good resistance to abrasion. Inclusion of a cutter simplifies preparation, allowing clean, straight cuts and reducing frayed edges. The assortment format saves time when repairing or organizing wiring and supports color-coding for identification.
Suitable for
Insulating soldered connections and splices in electronic circuits
Protecting and organizing automotive wiring and connectors
Repairing household appliance cords and low-voltage cables
Color-coding wires for installation and maintenance
Providing strain relief at cable exits and connector joints
Key specifications
Quantity: 128 pieces total including a manual cutter
Material: polyolefin heat-shrinkable tubing
Assorted diameters and lengths to fit common wire gauges
Shrink ratio: typical heat-shrink behaviour for secure fit after heating
Function: electrical insulation, abrasion protection and strain relief
How to use
Slide an appropriately sized sleeve over the wire or joint before making the electrical connection. After soldering or joining conductors, position the tubing centrally over the area to be insulated. Apply heat evenly using a heat gun, hot-air tool or controlled flame until the tubing contracts and conforms to the underlying shape. Trim excess with the included cutter prior to shrinking for a precise fit, and allow the tubing to cool before handling to ensure proper adhesion and mechanical stability.
Usage recommendations
For consistent results, choose a tube diameter slightly larger than the unshrunk wire bundle so that it can slide on easily, then confirm full contraction after heating. Use a regulated heat gun or hot-air tool rather than direct flame to avoid uneven shrinking or damage to surrounding insulation. Observe safe working distances and ventilate the workspace when shrinking multiple pieces.
