## Description

Product description HEAT ACTIVATED ADHESIVE Creates a resistant seal Greater tensile strength Resistant to stretch and vibration 4:1 SHRINK RATIO Recovers to 1/4 of its original diameter 4:1 Tubing is softer tubing than 3:1 4 1 Tubing slid RESISTANT Connection is sealed from the elements Protection against wire corrosion Can be submerged under water Super Versatile Heat Shrink Tubing Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief? Wirefy resistant heat shrink tubing is an easy to use solution that can be used in automotive, hobby RC, and home electrical wiring projects. It can be used in a variety of applications such as Electrical insulation (wire repairs, insulating electrical terminals wires, protecting charging cables, insulating solder joints) Environmental seal to protect from moisture, UV and fuel Strain relief for electrical terminals Identifying wires and cables (color-coding) Grouping loose wires (usually in wire harnesses) Creating thermal insulation for heat sensitive components Protecting surfaces against abrasion, peeling, and denting 4:1 Shrink Ratio Shrink Tube When heat is applied, this wire shrink wrap tubing will recover to a 1/4 of its original diameter. Its high recovery ratio makes it possible to repair most damaged cable jackets without removing larger connectors. Therefore, 4:1 shrink ratio tubing can be used in significantly more applications compared to 3:1 and 2:1 shrink ratio tubing. Additionally, 4:1 heat-shrink tubing shrinks around wires and terminals more tightly, eliminating any air gaps. Heat Activated Adhesive Lining This is a resistant shrink tubing with the internal adhesive layer. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat activated glue strongly adheres to wires, terminals or any other surfaces. When adhesive flows, it pushes the air out and fills any gaps between the wire and the tubing, which makes the connection resistant. For best results we recommend using a heat gun. Dual Wall Shrink Tubing Dual wall heat shrink tubing provides better rigidity and abrasion resistance. Dual wall tubing design has the increased ability to stand up to wear and tear. This wire heat shrink tubing is perfect for everyone. This industrial grade heat shrinkable tubing is compliant with all relevant electrical standards such as: SGS, RoHS, Reach, and ISO9001. Our Collection of Heat Shrink Tubing Wirefy assorted heat shrink tubing comes in kits as well as 50 Ft rolls. We offer a great variety of sizes (3/32” to 2”) and colors (black & red).

Review: Nice Product - Good product & will order again in the future
Review: beware of this company - I received this product in a timely manner, a week or so ago. Last weekend went to use it and after about 9ft. I found it had a splice in it. I don't know about you but if you have any cuts in a piece of shrink tube you should just scrap that piece and cut another which I had to do. The job I'm using it on has 3 wire runs at 10.5 ft. each. So now I have a piece that is 9ft long. Thanks for trying to get over on scabbing a piece of shrink tube onto the end of the roll, just a sad thoughtless act. Would have given them 5 stars but when you have a company that is willing to scab pieces together of a produce that it is ludicrous to have that thought is one that doesn't need my business.

## Features

- GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection. This creates resistant and long-lasting insulation.
- EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds.
- DUAL WALL TUBING - Provides enhanced protection from wear and tear. a resistant tubing is resistant to fluids, heat, and mechanical stretch.
- 1" (24.0mm) SHRINK TUBING DIAMETER - Get the exact diameter you need. 50 Feet of shrink tubing will last through many projects.

### ⭐⭐⭐⭐⭐ The level of ratio is surprising...
*by V***K on June 2, 2022*

oh, this is really a very good heat shrink tubing. The level of ratio is surprising. Something like a universal heat shrink tube, expands the range where it can be used and there is no need to purchase additional sizes heat tubing In addition to the excellent ratio (4:1) after it shrink, it releases something like glue from the inside so it's fashionable to be sure that it does not come off, in the video you can see this adhesive and how difficult it is to take off even after applying its maximum shrink properties
