Review: Very good product - I have been building a battery bank that required lots of cables of varying diameters that I then sleeved with braded loom and followed up by locking everything together using this heat shrink. The shrink rate of this stuff is kind of crazy, I've used it on wire as big as 4/0 awg all the way down to 4 awg and it happily adjusted its self to all of them. I dose require a fair bit of heat to get it fully shrank down and the glue inside melted but once that magic temp is reached it wastes no time about squeezing out some glue and sealing up the connection nice and tight. I honestly couldn't be more pleased about the results I've had using it. Highly recommend!
Review: Don’t Shrink Away From This Great Product - I love this stuff. I use it in crafts as an option to connect or tie into another aspect if the project. Projects that may involve tubes or pipe or those cardboard tubes. Because this stuff comes in all kinds of sizes. Plus let’s just say it gives me the reminiscent feels of playing with shrink-a-dinks as a kid. Oh and it does its job on wires and such too. Much nicer and cleaner look that gives me confidence that my repairs are safe.

## Features

- The Round Diameter is 1-1/2" / 40mm (Before Shrinking) and 1/2" / 12.7mm (After Shrinking). For packaging convenience, we pressure the tubing into a packing size of 2-1/2" / 63.5mm
