## Description

Wirefy Heat Shrink Tubing Kit 190 PCS - 4:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black & Red - Shrink Wrap Tubing | UL Listed: desertcart.com: Industrial & Scientific

Review: Cut to fit and worked like a charm. - Solid choice. I was making a light project for the wife and needed some heat shrink I could place over the wiring so it looked less DIY. This was the perfect choice. I was able to cut the length I needed, slide it over the wires and then heat it to a nice snug fit using my heat gun. The 1:3 shrink rate is highly accurate and my only suggestion would be to cut less than you need since it will extend as it shrinks. Overall, easy install and great value for the money.
Review: Wirefy Heat Shrink Tubing Kit: A Versatile and Durable Solution for Electrical Insulation - I recently purchased the Wirefy Heat Shrink Tubing Kit (180 PCS - 3:1 Ratio Adhesive Lined), and I am extremely satisfied with its performance. Here's a detailed review based on my experience: ### Comprehensive Kit This kit includes 180 pieces of heat shrink tubing in seven different sizes ranging from 3/32" to 3/4". This variety ensures that I have the right size for any project, whether it's small electronics or larger cable repairs. The pieces are precut to 3.5 inches, which is very convenient for quick applications​:citation[oaicite:6]{index=6}​​:citation[oaicite:5]{index=5}​. ### Superior Shrink Ratio The 3:1 shrink ratio is particularly impressive. It recovers to one-third of its original diameter, providing a snug and secure fit over various wire gauges. This feature eliminates the common issue of 2:1 tubing not shrinking tight enough, ensuring a professional and durable insulation every time​:citation[oaicite:4]{index=4}​. ### Adhesive Lined for Extra Protection What sets this kit apart is the adhesive lining inside the tubing. When heated, the adhesive melts and flows, creating a waterproof seal and providing excellent insulation. This feature is especially useful for automotive, marine, and outdoor applications where moisture resistance is crucial​:citation[oaicite:3]{index=3}​. ### Easy to Use Using this heat shrink tubing is straightforward. Simply slide the tubing over the connection and apply heat with a heat gun. The tubing shrinks quickly and evenly, making it easy to achieve professional results even for beginners. The dual-wall construction adds extra durability, with the outer wall providing abrasion resistance and the inner wall creating a strong adhesive bond​:citation[oaicite:2]{index=2}​​:citation[oaicite:1]{index=1}​. ### Excellent Value for Money At $14.99, this kit offers great value. The quality of the tubing and the comprehensive selection of sizes make it a cost-effective solution for a wide range of electrical insulation tasks. Free expedited shipping and returns add to the overall value, making it a hassle-free purchase​:citation[oaicite:0]{index=0}​. ### Final Thoughts Overall, the Wirefy Heat Shrink Tubing Kit is a high-quality, versatile product that meets all my electrical insulation needs. Its easy application, strong adhesive lining, and durable dual-wall construction make it a must-have for any DIY enthusiast or professional. I highly recommend this kit for anyone looking for reliable and effective heat shrink tubing.

**Q: Can it be used with self regulating heat cable**
A: Hi,

We do not recommend it because it will generally be kept at a higher temperature, up to 120℃, occasionally as high as 175℃.

**Q: Can this be used to cover banana plugs in use with speaker wire?**
A: Thank you for your question. Yes, it can be used to cover banana plugs in use with speaker wire.

**Q: Can these be used to reinforce the wire leading to earbuds? The rubber has ripped exposing a small window of the wires.**
A: You could if you are very careful as the heat needed to use for these could very easily melt the wires for your ear buds. You may be better off using liquid tape.
