PING-180 Pieces Black Waterproof Heat Shrink Tubing Kit - 3:1 Double Wall Heat Shrink Tubing - Adhesive Liner - Thermo Tubing

SHRINK RATIO 3:1 - Recovers one third of its original diameter and ensures an optimal seal. Eliminates the problem of 2:1 tubing not shrinking enough.GLUE INSIDE - When heat is applied, the glue comes out and seals the connection, creating a tight, long-lasting insulation.VARIETY OF SIZES - We have included 7 most commonly used diameters ranging from 2.3mm to 19.05mm. Heat shrink tubing comes pre-cut to 89mm.EASY TO USE - Simply slip the heat shrink tubing over your connection point and apply heat. Professional connections made in seconds.DOUBLE WALL TUBING - Outer wall provides abrasion resistance. Inner wall creates a tight seal and strain relief.HEAT ACTIVATED ADHESIVECreates a tight sealGreater tensile strengthResistant to stretching and vibration3:1 SHRINK RATIORecovers one-third of its original diameterMore versatile than 2:1 sheathNo air gap between wire and sheathWATERPROOF< p>Connection is waterproofWire corrosion protectionCan be immersed in waterSuper versatile heat shrink tubingLooking to repair a damaged wire, seal out moisture, or provide better strain relief? Waterproof heat shrink tubing is an easy to use solution for automotive, marine, DIY and home electrical wiring projects. It can be used in a variety of applications such as:Electrical insulation (wire repair, electrical connector wire insulation, load cable protection, solder joint insulation).Environmental seal to protect against moisture, UV and fuelStrain relief for electrical connectorsWire and cable identification (color coded)Bundling loose wires (usually in wire harnesses)Creating thermal insulation for heat-sensitive componentsProtecting surfaces against abrasion, peeling and denting.3:1 shrink ratio Shrink tubingWhen heat is applied, this heat shrink tubing shrinks back to one-third of its diameter d 'origin. Its high recovery rate makes it possible to repair most damaged cable jackets without removing the connectors. Therefore, 3:1 heat shrink tubing can be used in many more applications than 2:1 heat shrink tubing. Additionally, the 3:1 marine heat-shrink tubing shrinks more tightly around wires and connectors, eliminating any air gaps.Heat-activated adhesive linerIt This is a waterproof heat shrink tubing with the inner adhesive layer. When heat is applied, the heat shrink tubing will straighten and the inner adhesive layer will melt. A small bead of clear adhesive (approximately 1mm wide) becomes visible at the end of the heated sheath. Once cooled, it forms a rigid seal. Heat activated glue bonds strongly to wires, connectors or any other surface. As the glue flows, it pushes out the air and fills the gaps between the wire and the tube, making the connection watertight. For best results, we recommend using a heat gun.Double-Wall Heat-Shrink TubingMarine-grade double-wall heat-shrink tubing provides improved rigidity and resistance to abrasion. The design of the double-walled jacket gives it an increased ability to resist wear. This metal wire heat shrink tubing is flame retardant.
