As a result of using this 70mm diameter polyolefin, I found that it’s a remarkable choice for wiring and connecting electrical parts with exposed wiring. It’s incredibly easy to use and shrinks down to the metal neatly and without any stress .The tubing WILL allow you to insulate conductors, and the material can handle a wide range of temperatures. However, the only downside is that it may come up short for massive applications that the tubing wasn’t designed for. Still, it serves the purpose and is, without a doubt, an excellent tubing option..
