The heat shrink butt splice is an irradiated thermally stabilized heat shrinkable dual wall sleeving composed of an outer tube coated on the inner surface with a meltable polyamide adhesive.
Simply put: it's a piece of dual wall heat shrink with a crimp splice inside of it. You crimp the two pieces of wire together, and then heat the splice with a hot air gun so that the outer sleeve shrinks and the adhesive melts and flows to give a fully sealed water tight joint.
The butt splice is resistant to water, spray, oil, saltwater and most hazardous chemicals.
