About This

• 3:1 Shrink Ratio for Secure Fit— Our 1-inch heat shrink tubing starts at a 1-inch (25.4 mm) diameter and shrinks down to 21/64 inch (8.4 mm). With a high 3:1 shrink ratio, it provides a snug, reliable seal and superior protection, outperforming standard 2:1 tubing for a tighter fit.
• Dual-Wall Design for Durability— Featuring a rugged outer wall, this tubing is resistant to abrasion and corrosion, providing excellent insulation. When heated, the inner adhesive layer melts to create a clear, watertight seal that protects against dust and contaminants, ensuring a long-lasting connection.
• Easy to Apply— Simply slide the tubing over your connection and apply heat evenly. Our heat shrink tubing works effectively between 80°C to 125°C (176°F to 257°F) and withstands extreme temperatures from -55°C (-67°F) to 250°C (482°F) for dependable performance.
• Versatile Applications— This 1-inch (25.4 mm) black heat shrink tubing roll includes 32 feet (10 meters), ideal for electrical work, automotive repairs, industrial projects, and marine applications. Cut to your desired length to fit a variety of DIY and professional needs.
