Wirefy Heat Shrink Tubing Kit - 3:1 Ratio Adhesive Lined, a resistant Shrink Wrap - Automotive Industrial Heat-Shrink Tubing - Black, Red - 200 PC...

They work well. Kit comes with various sizes, but they give you a lot of the very small wraps which you use less of, so balance of quantity is off a bit

Perfect product for heat shrinking. I was working on a messy wiring project, with lots of cutting and splicing. These heat shrinks made the final product come out looking incredibly clean and professional. Furthermore, the adhesive that is advertised is incredibly helpful for securing and sealing.

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.

I've used this heat shrink on multiple car audio installs and it is awesome! I like that the case is small and can fit in my toolbox and not take up a huge amount of space like the rolled sleeving. The pieces are long enough for larger connections and are a good size if you need to cut them shorter. The ratio is perfect for all listed gauges of wire and it does a great job of securing the braided sleeving or wire ferrules. Best sleeving out there for the cost!
