There are many various kinds of heat shrink tubes, some of them are of worrying quality and cannot work after heating shrinkage; some of them have a lot of quantity, but the small size may account for 30%-40% of the total, do not be confused, for example, 1.6mm, 2.4mm heat shrink tubing, they shrink to less than 1mm in diameter, so these sizes are not used in daily life.
ALEKOR 3:1 dual wall heat shrink tubing sets are commonly used sizes, the smallest size is 3.2mm and the largest size is 19.1mm, exactly the size we commonly use in life, making every penny spent worth it. ALEKOR heat shrink tubing is the best option for wire insulation.
High Shrink Ratio Shrink Tube
For waterproofing connectors and wires, this ALEKOR 3:1 industrial heat-shrink tubing is one of the best solutions, it is more resistant to stretching and vibration than regular heat shrink and has more tensile strength, this allows for an extra tight fit that is hard to achieve with tubing that only shrinks to half its size (2:1).
A higher shrink ratio can be useful in applications where you need a tighter fit, or when you need to slide the heat shrink over a connector that is significantly larger than the wire that it is connected to.
Waterproof Dual Wall Heat Shrink Tubing
Adhesive lined heat shrink, also known as marine grade heat shrink, is made up of two layers. When adhesive-lined tubing heats up, the adhesive melts at the same time as the outer layer shrinks, adhesive flows into the small leftover cavities between the heat shrink and the object that is being sealed, after the tubing and adhesive have cooled down, is a watertight seal. Ideal for boat cars or hobby RC projects where splashing water is a frequent occurrence.

Works as it should and the adhesive sealant works well too! No more risk of water ingress.
