Video Transcript for Deka Primary Wire Heat Shrinkable Tubing Review

Today we're going to be taking a look at Deka's Shrinkable Tubing. These are available in either red or black and gauges between 2-8, 8-12, 10-14, or 14-18. You'll want to use heat shrink to cover up any exposed surfaces, especially on power circuits. We've got some here covering up the ends of our ring terminals where we've crimped it onto our battery wires. We also used it here where we connected two wires together using a non-insulated crimp. And you can see we've used it again here on a larger gauges.

You want to make sure that you use the appropriate size for the gauge wire you are working with.It's a shrinkable EDA tubing that is slightly larger than the gauge you're working with when you're using that appropriate size. You slide it over the wire before making your connection. Once you've made your connection you slide the shrink tubing back over the exposed wire and apply a heat source. I recommend using a heat gun. If you need a heat gun you can pick on up here at

You can see here as the heat source is applied to it the tubing shrinks tightly over our exposed wiring keeping out any moisture and corrosion that may occur. And that completes our look at Deka's Shrinkable Tubing.
