328-piece multicolor heat-shrink kit

This kit supplies 328 pieces of heat-shrink tubing in five colours for electrical repair, insulation and strain relief. It covers a range of diameters from 1 mm to 14 mm with lengths of 40 mm or 80 mm. The assortment suits hobbyists, technicians and anyone needing colour-coded wire protection.

Shrink ratios and heat requirements

Each tube shrinks to half its original diameter when heated between 70°C and 125°C. A heat gun or lighter held roughly half an inch away activates the shrink; the tube must cool completely before handling. No additional adhesives or tools are required beyond a heat source.

Bulk packaging and colour coding

The pieces arrive in a bulk pack without a retail box, keeping the kit compact for storage. Red, green, blue, yellow and black tubes allow quick visual identification of circuits or voltage levels. The variety of sizes and colours reduces the need to buy separate packs for different jobs.

Questions about this item

At what temperature does the tubing start to shrink?

The tubing begins to shrink at a minimum of 70°C and reaches full shrink at 125°C.

How hot does the heat source need to be for all-day use?

A heat gun or lighter held about half an inch away provides enough heat; the tubing shrinks quickly without prolonged high temperatures.

What heat source is required to activate the tubing?

A heat gun or a standard lighter held roughly half an inch from the tube will shrink it to half its diameter.
