Wire wrap kit contents

This Unique-Bargains assortment provides 144 pieces of 2:1 heat shrink tubing in six diameters. The kit covers 1 mm, 1.5 mm, 2.5 mm, 3 mm, 5 mm and 6 mm sizes with 24 tubes of each. Every piece measures 70 mm or 2.8 inches before shrinking. Polyolefin material delivers insulated protection for wire harnesses.

Who this suits and who it does not

Hobbyists and technicians needing a broad range of small-diameter sleeves in one pack will find the 12-colour assortment convenient. Buyers who require larger diameters, higher shrink ratios or adhesive-lined tubing should look at other products. The 70 mm length may be too short for long continuous runs. No dispensing box or organiser is included.

Deciding specification

The 2:1 shrink ratio means each tube reduces to half its supplied diameter when heated. Combined with the six specific sizes and 144-piece count, this ratio determines whether the kit covers the wire gauges you regularly terminate.

Questions about this item

How do I apply the 70 mm polyolefin tubes so they shrink evenly to half their diameter?

Cut the required length, slide it over the wire joint, then apply heat evenly around the tube until it shrinks to half its original diameter; the most common mistake is heating one spot too long, which causes uneven shrinkage or scorching

What maintenance or replacement will the heat-shrink tubing need after installation?

Once fully shrunk the polyolefin forms a permanent seal; no routine maintenance is required, and the tubing only needs replacement if physical damage cuts or cracks the insulation

What is the first limit that appears when the tubing is exposed to sustained heat near its shrink temperature?

The material starts to shrink at 70 °C and reaches full shrinkage at 11 °C; operating continuously at or above the start-shrink temperature will cause gradual dimensional change and loss of grip on the wire
