Wrap-Around Heat Shrink Tubing: How to Insulate Cables Without Unplugging Them First

wrap-around-heat-shrinkToday, let’s talk about the things that you, in retrospect, should have thought of earlier. Things like letting your newly housebroken puppy out before you left for the night. Closing the garage door when you peeled out of the driveway, headed for the airport. The fact that a first name like Moonbeam or Ruckus might thwart the career goals of your child, who is now 17 and aspires to become a Supreme Court Justice. Or maybe just the possibility that vital network cables or electrical wiring that can’t be temporarily disconnected post-install would someday need a little extra insulation or strain relief.

I can’t do anything to help with the gross spot on the carpet, stolen lawn mower, or bitter, upwardly-mobile teenager, but those undisconnectable cables aren’t as big a deal as you might think.

Thanks to Zippertubing’s very cool new line of wrap-around heat shrink tubing, it’s easy to repair or add some extra protection to cables that you either can’t, or would just prefer not to, unplug. Unlike traditional heat shrink that needs to be slipped over connectors and slid along the length of the cable you’re trying to cover, wrap-around heat shrink is slit along its length, so that you can slip it around cables from the side.

You’re probably thinking the same thing I was when I first heard about this tubing: “Soooooooo… what happens to the slit when you start to shrink this stuff?” The answer is: nothing. Because thanks to an adhesive strip along one edge, the slit is nonexistent by the time you get around to applying heat. Once the sleeving is positioned the way you want it around the cable, you just peel the backing off the adhesive strip and press it against the other side, sealing everything into a solid tube.

Once that’s done, shrink away – you’ll end up with well-insulated cables that won’t leave you feeling even the tiniest bit of regret. I just wish I could say the same for poor Moonbeam.
