What is heat shrink tubing?

Heat shrink tubing is a type of plastic layer which can be used on cabling and components for a variety of purposes such as: electrical insulation, protection again dust, chemicals, abrasions and moisture, reinforcement, identification, and consolidating multiple wires into a single unit. They are also known as heat shrink sleeves. The wrap is secured to the desired components by heating it with a heat gun or heat shrink oven. To choose the best sized tubing for your installation you will need one that is 20-30% larger than the widest part of the cabling it is being used on.

What is shrink ratio?

This term refers to how much the tubing will shrink following its application, compared to its original size. For example, a 2:1 means that it will reduce to half its size. Higher numbers make for a tighter fit.
