About this item
- 3:1 HEAT SHRINK RATIO: Dual-wall heat-shrink tubing will shrink down to 1/3 of its original size when heat is applied, perfect for wire terminations or exposed insulation; The melting adhesive forms a waterproof, hermetic seal with >10.4 MPa tensile strength and 15 kV/mm dielectric strength, ensuring durable, insulated connections even in harsh environments
- High Quality for Versatile Application: This 3/4" high-quality heat-shrink tubing with adhesive is ideal for industrial repair, marine, automotive, wire bundling, electrical insulation, and DIY car audio; It protects solder joints from rust and corrosion while offering mechanical durability; With an operating temperature range of -55℃ to 125℃, it ensures reliable performance in extreme conditions
- How to Use: 2 easy steps to seal the connections; 1. Cut the heat shrink tube in the length you required from the roll and slide it over your connection point. 2. Use a heat gun or hot air blower to shrink the tubing at its full shrinkage temperature of 120℃ to seal the connection; That's it! Enjoy the peace of mind that comes with a secure, airtight seal
- Durable & Reliable Protection: The heat shrink tubing roll is perfectly sized at 3/4", offering ample length for various applications; It provides a secure fit for your wiring needs and ensuring reliable protection against abrasion, moisture, and environmental damage while also offering flame-retardant protection
- Package Contents: This package includes a 50 feet roll of 3/4" black dual wall polyolefin adhesive heat shrink tubing, providing secure insulation and protection for your wiring projects
