3 1 Marine Grade Dual Wall Heat Shrink Tubing Roll 1

ALEKOR heat shrink tubing is the best option for wire insulation. Aside from its excellent insulating properties, it comes with a variety of other useful features, like its ability to bundle cables, add strain relief, or be effective for waterproofing irregular-shaped objects. This adhesive-lined 3:1 ratio heat shrink tubing creates a tighter fit around the target components and, once melted, its adhesive forms an impenetrable seal. Heat shrink tubing has many useful applications, including providing electrical insulation to wires, connections, joints, terminals, and splices, as well as bundling loose items such as wires and as a protective covering.When used as a protective covering, heat shrink protects from abrasion, cutting, scuffing, and low impact situations. 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.
