Product Details
✓Excellent Shrinkage Performance: Unrecovered diameter: 1/2" (12.7 mm), recovered diameter: 11/64" (4.2 mm). Upgraded with a 3:1 shrink ratio, it can retract to 1/3 of its original diameter, ensuring a tight seal. This eliminates issues seen with 2:1 wire shrink tubing that may not shrink tightly enough
✓Efficient Connections: Our shrink tubing for wires features an dual wall adhesive lining. When heat is applied, the inner wall's glue film melts and tightly adheres to the object's surface, creating a waterproof and long-lasting protection (Shrink temperature: 80 to 125°C)
✓Premium Quality Wiring Heat Shrink Tubing: Crafted from polyolefin, it offers excellent electrical insulation, sealing, corrosion resistance, and high-temperature resistance. It is durable, anti-aging, and resistant to breaking
✓Easy to Cut and Install: The heat shrink tubing has a total length of 33 feet, allowing you to easily cut it to any desired length for various projects. Simply slide the tubing over the object you wish to protect, then apply heat from a heat source to shrink and secure it. This creates a professional and strong connection in just a few seconds
✓Wide Range of Applications: Ideal for protecting against rust and corrosion in industrial, marine, and electrical wire connections, as well as solder joints. It's also perfect for audio and electrical DIY projects, providing protection for the ends of headphones and telephone cables
✓Note: To ensure the correct size of Heat Shrink Tubing is ordered, please confirm the exact diameter needed before purchasing to guarantee a proper fit. The initial diameter of the round shrink tube is 12.7 mm (1/2") before shrinking
✓Warm Reminder: Please note that the product packaging has been updated. You may receive either the new or old packaging as we transition between the two. The product quality remains unchanged
