A: This tubing is the perfect way to insulate and protect your cables and wires from harmful elements. It also provides extra durability and heat resistance for you cables.
Q: What does the ratio on the Heat Shrink Tubing mean?
A: The ratio provides the size of the original Heat Shrink Tubing as compared to the size of it after it has been heated and shrunk. We carry 2:1 ratio Heat Shrink Tubing. This means that after being heated the tubing will be half of its original size.
Q: How do I know what size to buy?
A: It is very important to measure whatever you are planning on covering before you order our Heat Shrink Tubing. Buy tubing that is larger in diameter by about 20-30% then what you plan on covering. This is to assure that there is room to move and adjust the tubing around your cables and wires. Also you should buy a piece that is longer than you think you will need due to a slight shrinkage that might occur lengthwise of about 5% during the heating process.
Q: How is heat shrink measured?
A: The size of the heat shrink is the measurement of the diameter. There are two ways to determine the diameter. For smaller tubular heat shink it is the measurment from end to end. For larger heat shrink that is shipped flat it is the flat width multipled by 2 and divided by PI. Width x 2 / π. This calculation gives you the diameter of the heat shrink when it is opened to its full circular size.
Q: What kind of tool do I need to use in order to shrink the tubing?
A: You will need a heat gun to shrink your tubing. We sell one that will get the job done! It is located on the Accessories Tab.
