Yes, there is a special version of this that has a gooey adhesive which melts and expands at the same temperature that the heat shrink shrinks. This ultra adhesive locks itself down onto whatever it touches and shifts some of the load for keeping the stuff inside onto the heat shrink itself. It also doubles as a waterproof barrier, and as such, this tubing is usually referred to as marine grade heat shrink.

As we said before, there are thousands of uses for heat shrink tubing, from its intended purpose of protecting wiring, to being manipulated to be an end cap for a bolt or a sleeve for abrasion. If you can dream it, heat shrink can do it—and it is cheap.
