Gabriel
Verified Buyer
Using a heat gun they provided and it was super easy to slip it on, twist the wires and slip it back on to solder and seal in one swoop is wicked cool! Very happy! Gave them
William
Verified Buyer
Work excellent! Seal AND solder wires together! I just hit them for about 15 seconds with my heat gun till shrink tube shrunk then solder melted to wire leads...boom, done!
Brad
Verified Buyer
This solder sleeve works exactly how it is described & kills two birds with one stone of soldering wire as well as sealing the connection. It is a huge time-saver.
Kevin
Verified Buyer
After about 5 seconds the rubber material started to shrink. At about 9 seconds the solder started to melt & bond the wires. I gave the wires a firm tug & there were super tight.
Frequently Asked Questions
Heat shrink tubing is used as insulation for electrical components. It also protects them from external factors like moisture, dust, and abrasion.
It is ideal to use a heat gun to shrink heat shrink tubing. Hold the heat gun 3 to 6 inches from the tubing and move the nozzle back and forth until the tubing fits snugly around the wire.
If you do not have a heat gun, you can also use a lighter or a hair dryer to shrink heat shrink tubing. Hold it an inch away from the tubing and move it back and forth to distribute the heat evenly.
Standard sizes of heat shrink tubing include small diameters like 1/16 inch to larger diameters like 1 inch or more. You can also see them in different shrink ratios, such as 2:1 or 3:1. These various sizes are designed to fit different wire gauges and connections.
Heat shrink tubing has many benefits, such as cable protection, insulation, stress resistance, organization, and corrosion resistance.
