Heat shrink tubing roll - 4:1 ratio

Great stuff! The 4 to 1 makes this really versatile.

Shrinks up really well- I used it to hold two battery cables together for the RV. The glue does a great job of expanding to create a watertight seal between two cables.

This heat-shrink tubing has a good heat-activated adhesive inside of it. There is a good amount of shrink that doesn't require a crazy amount of heat. This tubing is easy to use and stays in place. Not thin walled.

I have tried a few dozen different brands over the years, but nothing as compared to the quality of this 4-1 heat shrink. 100% the best we have ever used. We make custom harness’s for use in the custom truck accessories market and use a couple rolls a month. Once you heat shrink something with this product it’s there for life. The adhesive inside it must be a structural product because it’s amazingly strong and water proof.

When in doubt, go up a size. My 1/2" would not fit over something that was 0.47".Other than that, it's great.

I built a DIY 12 channel TRS snake for my studio and the Wirefy heat shrink was a vital part of the success of the project. This product is exactly as advertised and works as good or better than anything I have used prior. This shrink wrap has a very solid water tight look to it and appears as if it will stand the test of time. The 4:1 ratio of shrinkage is an awesome feature as this saved me from buying different sizes of the product. One size met my needs beautifully. I really like how the heat creates a nice little clear plastic seal on each end of the wire. This should provide an extra degree of insulation and stability to my connections on both ends of the snake. I build allot of electronic projects and I make many homemade audio cables for my guitar rig and studio. This will now be my goto choice for shrink wrap in the future.

I had ran out of 1/4" heat shrink and gave this a try. It works well and shrinks tightly making a great sealed connection. Will not slip on the wire once it has been shrunk. I use a heat gun to shrink.

Good product & will order again in the future
