1-1/2 Inch 3:1 Large Marine Grade Adhesive Lined Heat Shrink Tube Wire Wrap

Today’s purchases are four foot rolls of both black and red large heat shrink for electrical applications. They came sealed and packed together. I wanted red and black heat shrink for my car audio installations. This purchase allowed me to conveniently buy, not only both red and black together, but the rolls allow me to cut them as long or as short as I need at the moment. I used them to distinguish between the power and ground wires since the insulation is the same color. It also made the install much cleaner looking and protected the install from shorts. These sheat shrinks seem to have an additional adhesive on the inside, meaning once they are on, they are not coming off. This is really great for securely protecting your equipment, but not so great if you have to remove them. I recently started getting into using the heat shrinks, but now that I am, I want everything to have shrink on it. These tubes are super easy to use and work on a wide range of sizes, shrinking up to four times. The quality and results that you get from these are great, and they are very affordable, making them a very good deal. If you like using heat shrink, and you are looking to get some or replenish your stock, I would highly recommend these, because they are a great value.

Worked great. It really does shrink way down.

I have used heat shrink tubing for a lot of applications in electronics. This time, however, I used the 3/4 inch heat shrink so I could use it for insulation grips on a number of older pliers in my tool box. I thought at first 3/4 inch may have been too large, but the 3:1 shrink ratio was perfect, and my hand tools look great after applying the stuff.

Works as designed. When applying heat, slow even heat worked best for me. Start at one end and slowly work to the other end.

​This marine-grade heat shrink tubing is absolutely exceptional and made my handlebar swap an absolute breeze. * Perfect for Handlebar Swaps: I used this to bundle and protect the control wires for a handlebar swap on my Harley Street Glide. The 3:1 shrink ratio gave a tight, perfect seal over the connections, keeping the harness slim enough to pull through the bars effortlessly. ​Excellent Heat Tolerance: It handles heat incredibly well during application. It shrank down evenly without burning, splitting, or getting brittle, and the internal adhesive flowed perfectly to create a solid, weatherproof barrier. ​Top-Tier Quality: The thick, marine-grade wall offers awesome abrasion resistance inside the bars where things can rub. ​If you're doing any internal motorcycle wiring or bar swaps, don't hesitate—this stuff is top-tier.

Thick, durable and good shrink ratio

worked as expected

Exactly what I needed, has the adhesive in it so it's super durable. the red is red, not orange so color is spot on. super thick and flexible for it's thickness. and exactly what I need for heavy gauge wire. Compatible with pretty much anything. Super easy to use. use a heat gun and it shrinks and adheres perfectly. for the price I wish I got 10ft.

Excellent product and very good customer service

Font le job :-)

Ottima guaina termorestringente. Mi sembrava troppo larga per il mio uso ( connettori a banana per casse acustiche 6mm ) ma restringono molto e in più hanno un collante che solidifica tutto. Consigliato
