3:1 Marine Grade Dual Wall Heat Shrink Tubing Roll 1-1/4" 30ft Black

3:1
Shrink Ratio: This shrink tubing contracts to one-third of its original size when heat is applied, offering greater resistance to stretching and vibration than standard heat shrink, along with enhanced tensile strength.
Dual Wall Shrink Tube: Reliable, long-lasting adhesive-lined heat shrink tubing composed of two layers, providing waterproof and sealed protection.
Flame-retardant and Low Smoke: This electrical shrink wrap tubing is constructed from polyolefin with an inner layer of meltable adhesive, capable of withstanding temperatures from -67 to 257 degrees Fahrenheit (-55 to 125 degrees Celsius).
Easy to Use: Simply slide the heat shrink tube over your connection point and apply heat, creating professional insulated connections in seconds.
Widely used: Heat shrink tubing is primarily utilized for electrical insulation of wires, solder joints, connectors, and terminals; it can also serve to prevent damage, provide strain relief, bundle wires, and more. The size of this heat shrink tubing is indicated by its round inner diameter (diameter when round) and is delivered in a flattened state (flat width). For instance, a heat shrink tubing labeled as "2 inches (50mm) diameter" will have a flat width of roughly 3 inches (75mm). Please choose the appropriate size based on the round inner diameter
