It’s better than electrical tape, doesn’t unravel and lasts far longer
by KEITH BERGLIND
Heat shrink tubing is a simple product often overlooked for sealing electrical connections. This easy-to-install product does a better job than electrical tape and it lasts far longer than a few wraps of tape.
Electrical tape is always my second choice for covering any electrical connections. I plan most jobs to be finished and sealed with heat shrink tubing.
This means putting the tubing looseon the wire before doing the soldering, and before clamping or crimping any connection.
