Heat Shrink Tubing Kit 200 PCS - 3:1 Ratio Adhesive Lined, Wire Shrink Wrap Tubing - Industrial Heat-Shrink Tubing - Black & Red - Shrink Wrap Tubing | UL Listed

This is a nice heat shrink especially for the money. They have always held up good, even exposed to weather. They shrink up at a good temperature and have a good amount of adhesive that you can see come out after shrunk. Will continue to reorder this

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.

This stuff really works great. And definitely has the glue inside . Shrinks 3-1 ratio easy . I sealed a crack in a .5 " vac hose with the 3/4" and was amazed. It's a bit stiff but definitely strong connection..

This is a nice assortment kit. Though I do wish that it would come with more of the largest size, it only comes with two red and two black. Just enough for one set of wires (jumper cables). It would also be nice if those were longer. The length is great for the smaller sizes but not ideal on the largest. They did cover the connection okay but won't offer much in the way of strain relief at all. Longer length and thicker heat shrink would have been much better. That said, for medium thickness/duty this heat shrink seems to be nice quality. It shrinks well and has plenty of adhesive. It's definitely a nice assortment of sizes and quantity for the price, especially if your wiring is less than 4ga.

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.

Everything I need to re-wire my project and use Wirefy heat shrink. UPDATE: Used item today and it works great, the way it was intended to do. 5/7/2026.

Great product for the price! This set will last you a while with 275 pieces. are use this product for DC wiring in a vehicle, and I was really surprised with the quality of the product compared to similar shrink tubing I got from the automotive store. The real difference was the thickness of the rubber and the fact that there it was adhesive lined, which created a weatherproof, and essentially watertight seal, which will illuminate oxidation and corrosion, which could cause a short circuit in the future. The tubing will shrink when you heat it, and that he sieve will melt and create a very tight and strong seal. I was actually surprised with the quality of the seal. this is not an endorsement but I would highly recommend this product if you're looking for shrink tubing that only you issue percent is that a lot of the sizes are similar but the sizes are listed so you know exactly what you're getting it's just a lot of shrink tubing so it would be nice if there's a few different larger sizes, but the variety was good for the application of stranded wires, I was able to crimp the wires after sliding the shrink tubing on one end of the wires, once the wires was crimped I was able to slide the shrink tubing over the crimp and heat it up slowly with a small torch from about 5 to 6 inches away, as it shrinks after heated, the adhesive begins to melt and creates a very strong seal, I have use this product over a year ago and it's still standing strong. This is not a fake review or endorsement LMAO 🤣

These seemed to be good quality and waterproof.

a must to have on hand in the shop. Used for car wiring and to seal the ends with spade connectors to make a neat joint and protect the joint and reduce the chance of ingress. Also looks neater in engine bay - or wherever your using. Lots of different colours and size choice and inexpensive. Seal onto wire with a low flame on the blow lamp. But heat gun equally as good.

Très bon produit avec colle intérieure

Muy buena caja recomiendo es muy util!

Très bon produit, conforme.

Good quality but pricey, but if you are protecting electrics, then this is the one. Wish it came in shorter lengths, so I could have gotten a size down too. Shrinkage is uniform, have to cut open to re do and the wire comes away neatly which is also a bonus. Very durable but measured diameter wrong, but that's on me. I've used this on all my bikes wiring and seems solid so far.
