Wirefy | Heat Shrink Tubing - 3/4" inch - 3:1 Ratio - Adhesive Dual Wall Waterproof - Heat Shrink Tube - Heatshrink Tubes - Black - 50 Feet Roll | Trusted UL Certification

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.

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.

Very useful and complete set. The tubing shrinks evenly and seals well. Quality feels good, comes in a well-organized box with many size options. Works perfectly for wires and small projects. Definitely a reliable kit to have.

I’ve used this Wirefy Heat Shrink Tubing Kit for a few electrical fixes, and it seals tight and secure every time. The 3:1 adhesive-lined tubing is strong and waterproof, and the variety of sizes is really handy. It’s easy to use with a heat gun, and the UL certification is reassuring. Great value

I like the internal adhesive, and the shrink ratio of this tubing. I used it so far to repair some bared wires on a New Holland tractor relay wiring harness, which required de-pinning the plugs, and sliding the shrink tubing OVER female spade connectors. Most tubing would then not shrink small enough, but this easily shrank down small enough to do the job, with the added benefit of the glue sealing the end for rough outdoor use.

Nice to have around and they work great

They shrink smaller than most shrink tubing which is nice.

As described.. I like the internal glue which seals the end after heating. Good quality

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.

I ordered this product after research and reviews. Was not disappointed it’s really great stuff I’m a newbie in doing van electrics and solar install and wanted the wiring to be safely protected some may think it’s overboard but I wanted good coverage and sealing. This 4:1 heat shrink was so easy to use I did procrastinate on what size trying to work that out initially but once I got going it was fine I used a heat gun and then welding gloves to protect my hands. Anyway the result was just what I was hoping for and has given my cables of various thickness a really good wrap. Swift delivery and would have no hesitation in re ordering from this seller, many thanks.

Très bon produit, conforme.

Queste fascette termorestringenti sono veramente OTTIME. Valgono ogni centesimo. Robuste, ottimo assortimento, si restringono veramente sino a 4 volte. Prodotto davvero di qualità. L'unico appunto che potrei avanzare riguarda la scatola di plastica in cui sono contenute: Le cerniere posteriori non tengono e la scatola tende ad aprirsi. Un elastico ed il problema è risolto. Soddisfattissimo.
