Review of the Deka Heat Shrink Butt Connectors

Today we'll be taking a look at a Deka line of Heat Treat Butt Connectors, available in five and ten packs, in a variety of colors and gauges here at We have one of the butt connectors out of the pack, take a quick look at it. It's labeled twenty-two and eighteen gauge wires, and the center section here, the metal part, is the actual butt connector itself. On the outside you've got the nylon covering, and these two large ends are parts that shrink down after you install your wires. It's a good idea to use a good set of crimpers, and also make sure you have your wires stripped back to about maybe a quarter inch. Then just crimp it down, bring your other wire in and do the same thing.

Then we'll apply heat to the butt connector to shrink up the wires. It'll take up the openings and seal our connection from dirt and water. Ideally you want to use a heat gun. You can direct the heat with it. If you don't have a heat gun available a lighter works as well. Using lighters get it hot after a while so it may be a good idea to use a barbecue lighter instead.

Since you can't direct the heat with this you'll probably have to apply heat a little bit longer than normal for the top side to shrink up as well. We'll go ahead and show our heat shrink butt connectors in typical application. In this case it's going to be behind a trailer light. We'll apply heat to go ahead and shrink the ends down and make a seal around the wire. We'll go ahead and do a test run and verify we have connection through our butt connector.

That'll do it for our review of the Deka line of Heat Shrink Butt Connectors. .
