Black 400 Pcs 3:1 Heat Shrink Tubing + Black and Red 400PCS 4:1 Heat Shrink Tubing

• INCLUDES MORE ADHESIVE COATING: The adhesive on the inside of 4:1 heat shrink tubing will be thicker than the inside of 3:1 ratio, automatically releasing more adhesive and sealing the joint as the heat shrink tubing heats up. This creates a waterproof and durable insulation with a satisfaction quarantee.
• 4:1 SHRINK RATIO & FAST CONTRACTON SPEED: Shrinks to 1/4 of its original diameter for greater tightness and a 30% increase in sealing. Eliminates the problem of 2:1 and 3:1 tubing not shrinking tight enough. Heat Shrink Tubing shrink temperature: 80 to 125°C, Provides a professional connection within seconds.
• 3:1 SHRINK RATIO & FAST CONTRACTON SPEED: Shrinks to 1/3 of its original diameter and seals extremelytightly, solving the problem of many 2:1 shrink tubes that don't shrink enough and therefore don't sealtightly enough, Shrink temperature: 80 to 125°C, Provides a professional connection within seconds.
• DUAL WALL TUBING: The outer wall of the shrink tube provides extremely high abrasion resistance. The inner wall creates a consistently waterproof seal and excellent strain relief. Our solder connectors will also impress you!
• VERSATILE APPLICATIONS: Eventronic waterproof heat shrink tube can be used in marine and automotive wiring, model building, and DiY electrical wiring projects. The application areas are very diverse, such as electrical insulation/environmental sealing to protect against moisture, fuel and chemicals/protection of surfaces against abrasion, peeling and denting.
