## Description

Looking to repair damaged wire, seal moisture or provide better strain relief? Wirefy Adhesive Heat Shrink Tubing is an easy to use solution to insulate and protect wires, cables, connections and components. It can be used in a variety of applications: marine and automotive wiring, outdoor and home repairs, RC recreation, etc. It is a 3:1 heat shrink tubing which allows it to be used in many more applications compared to a 2:1 heat shrink tubing. When heat is applied, the heat shrink tubing straightens and the inner adhesive layer melts. A small net of transparent adhesive (about 1 mm wide) becomes visible at the end of the heated sheath. When cooled, it forms a rigid seal. Heat-activated glue sticks strongly to threads or any other surface. 275PCS Heat Shrink Tubing Kit Includes: -- 2.4mm Heat Shrink Tubing - 70PCS (15 Black, 15 Red, 15 White, 15 Clear, 10 Blue) -- 3.1mm Heat Shrink Tubing - 50PCS (14 Black, 14 Red, 8 White, 8 Clear, 6 Blue) -- Heat Shrink Tubing 4.7mm - 75PCS (25 Black, 25 Red, 10 White, 10 Clear, 5 Blue) -- 1/4" Heat Shrink Tubing - 45 PCS (15 Black, 15 Red, 6 White, 6 Clear, 3 Blue) -- 9.5mm Heat Shrink Tubing - 25PCS (8 Black, 8 Red, 4 White, 3 Clear, 2 Blue) -- Heat Shrink Tubing 12.7 mm - 5 PCS (5 Black) -- Heat Shrink Tubing 19.05mm - 5PCS (5 Black)

## Features

- 275 SHRINKING SLEEVES: From smallest 3/32" to biggest 3/4" - all pre-cut to 1.75" multicolored tubes. This heat shrink tubing is colored for easy identification and designed for reliable repairs.
- DUAL WALL TUBING: The outer layer provides abrasion resistance, while the inner adhesive bonds firmly to the wire. Ensures long-lasting electrical insulation and strain relief.
