Product Details
✓3:1 Shrink Ratio: Our 1/2-inch heat shrink tubing offers a non-shrunk diameter of 1/2" (12.7 mm) and shrinks down to 11/64" (4.2 mm). The high 3:1 ratio ensures a snug, reliable seal and providing superior protection, outperforming ordinary 2:1 tubing by heat shrink tubing.
✓Dual-Wall Design: Built with a rugged outer wall, this tubing is resistant to abrasion and corrosion, offering excellent insulation. Upon heating, the inner adhesive layer melts, creating a clear, strong seal that is waterproof and shields connections from dust and other contaminants.
✓Simple Application: Slide the tubing over your connection and apply heat evenly. Our heat shrink tubing shrinks effectively at temperatures from 80°C to 125°C (176°F to 257°F) and withstands temperatures as low as -55°C (-67°F) and as high as 250°C (482°F), ensuring dependable performance.
✓Versatile for Many Applications: Package includes a 1/2-inch (12.7 mm) black heat shrink tubing roll, totaling 32 feet (10 meters). Ideal for electrical work, automotive repairs, industrial projects, and marine applications, this tubing can be cut to your desired length, providing flexible protection for all your DIY and professional needs.
