4:1 Heat Shrink Tubing Kit, 500PCS Adhesive Lined Wire Tubing - size: white

About this item

• 4:1 High-Ratio Shrinkage And Rapid Shrink Speed: Heat shrink tubing Shrinks to 1/4 of original diameter for enhanced sealing and 35% improved performance. This resolves the insufficient shrinkage issues common in standard 2:1 or 3:1 heat shrink. Heat shrink temperature: 80 to 125°C, achieving professional connections within seconds and resolve question caused by insufficient shrinkage in traditional shrink tubing.
• Superior Adhesive Lined: The 4:1 shrink tubing features a significantly increased adhesive content—twice that of 2:1 products and 50% more than 3:1 models. This allows greater adhesive release during shrinkage, forming a stronger seal, enhanced adhesion, and superior waterproof heat shrink tubing resistance. Ensures connections remain durable and reliable in harsh environments.
• Dual Wall Tubing Protection Structure: Heat Shrink outer layer of wear-resistant tubing provides high-strength physical protection, while the inner layer of hot-melt adhesive forms a permanent waterproof seal upon shrinkage. This design delivers exceptional stress relief, ensuring a tight connection, insulation, corrosion resistance, and a perfect seal.
• Expanded Size Range for Real-World Use: Most 500 PCS heat shrink tubing kit include only common sizes. Ours shrink tubing features an expanded 8-size assortment to fit more wire gauges, delivering tight, professional seals that limited-size heat shrink kits can’t achieve.
• 500 Pcs Full Coverage Fit：This 500 PCS Heat Shrink Tubing kit features upgraded 45mm extended tubes for superior coverage.
