Review: Great product - This stuff works great.Not just for wiring,I’ve used it to insulate tool handles, patch cracked or chafed or otherwise damaged outer sheathing of brake or clutch cables on bikes etc.I’ve ordered several sizes of the rolls and multiple boxes of the pre-cut assorted sizes over the past few years. Comes either 3:1 or 4:1 shrinkage rates . Once you figure out what you use the most it’s great to be able to get 20-25’ rolls . It has adhesive on the interior that really makes a great seal for keeping moisture out.There may be comparable products out there but I am going to continue to use this brand. I think the price is fair and you get what you pay for.
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.

## Features

- 3:1 SHRINK RATIO: Wire shrink wrap tubing shrinks to 1/3 of its size for a tight, secure fit. Better than 2:1 tubing. Ideal for wire heat shrink tubing in electrical or automotive use.

### ⭐⭐⭐⭐⭐ Wirefy Heat Shrink Tubing Kit: A Versatile and Durable Solution for Electrical Insulation
*by T***H on June 19, 2024*

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.
