About This

• 3:1 Shrink Ratio for Reliable Sealing— Our heat shrink tubing, with a starting diameter of 5/8 inch (15.4 mm), shrinks down to 13/64 inch (5.1 mm) for a snug, secure fit. This high 3:1 ratio provides superior protection, outperforming standard 2:1 tubing by creating a tighter, longer-lasting seal.
• Dual-Wall Design for Maximum Durability— Engineered with a rugged outer wall, this tubing is resistant to abrasion, corrosion, and harsh environments. The inner adhesive layer melts upon heating, forming a waterproof seal that safeguards connections from dust, moisture, and contaminants.
• Simple and Effective Application— Just slide the tubing over your connection and apply heat evenly. Our heat shrink tubing shrinks efficiently at temperatures from 80°C to 125°C (176°F to 257°F) and withstands extremes as low as -55°C (-67°F) and as high as 250°C (482°F) for dependable, long-lasting performance.
• Versatile for Multiple Applications— This 5/8-inch (15.4 mm) black heat shrink tubing roll includes 32 feet (10 meters) of tubing, ideal for electrical repairs, automotive work, industrial tasks, and marine applications. Easily cut to any length to fit all your DIY and professional needs.
• Quality Assurance You Can Trust— Certified to ISO, RoHS, and SGS standards and UL recognized, our heat shrink tubing undergoes rigorous testing for safety and quality. For any questions or concerns, our support team is here to help.
