2 Pcs 1/2 inch (Diameter) Heat Shrink Tubing, 3:1 Adhesive-Lined Large Heat Wire Shrinkable Tube by MILAPEAK (4 Feet, Black & Red)

I bought some old vintage tools in a estate sale cleaned them and used this size to give protection and gripto the handles on channel lock wrenches and some pliers now these tools look sharp and new again.

Easy to shrink with a heat gun. Not quite a 3X shrink, but close. Good internal adhesive.

This stuff can shrink. I was surprised when it said it can to down to 1/3 of its size. I had a plug on 10 gauge wire I wanted to cover. It didn’t shrink down to 10 gauge but it was close. I had the right size heat shrink on the wire then did this 1/2” on top of that to get the plug. Worked great. It worked as I expected for 4 gauge. Good tight fit.

Would buy again

This is really good heat shrink and I always keep it on hand

I needed shrink wrap for a project on my travel trailer with 2 and 4 gauge wire. This did the job, was easy to work with and the glue sealed everything tight.

All in all very good, but noted more issues with red burning vs black.
