Product Details
✓Efficient Connections: Our shrink tubing for wires features an 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 insulation.
✓Excellent Shrinkage Performance: 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.
✓Premium Quality Wiring Heat Shrink Tubing: Crafted from polyolefin, this heat shrink kit offers excellent insulation, waterproofing, wear resistance, corrosion resistance, anti-aging properties, toughness, and durability.
✓Safe and Environmental: Our heat shrink tubing complies with RoHS standards and does not contain heavy metals or other environmentally hazardous substances. You can use it without concerns about harming yourself or the environment.
✓Wide Range of Applications: Perfect for industrial uses, ships, wire connections, and providing anti-rust, anti-corrosion protection for solder joints and insulation of electronic components using heat shrink tube. Additionally, it effectively safeguards headphones and phone 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 9.5 mm (3/8") before shrinking.
