Product Details
✓Efficient Connections: Dual wall heat shrink tubing has an adhesive lining. When heat is applied, the glue film on the inner wall will melt, and then it will be adsorbed on the surface of the object tightly, creating waterproof and long-lasting insulation
✓Good Shrinkage Performance: Unrecovered diameter: 1/4" (6.4 mm), recovered diameter: 5/64" (2 mm). The upgraded 3:1 shrink ratio allows it to recover to 1/3 of its original diameter, ensuring a tight seal. This eliminates the issue of 2:1 shrink tubing not shrinking tightly enough
✓Premium Quality Heat-Shrink Tubing: This heat shrink tube, made of polyolefin, offers excellent insulation, waterproofing, wear resistance, corrosion resistance, and anti-aging properties. It is tough and durable, ensuring it won't easily break. With a total of 32.8 feet of shrink tubing, you'll have enough for many projects. You can conveniently cut the heat shrink tubing to any length you need
✓Safe and Environmental: Our wire heat shrink tubing is RoHS compliant, and the material composition does not contain heavy metal and other environmentally hazardous substances. Don't worry about it hurting your body and environment
✓Wide Applications: Wire shrink wrap tubing is mainly used for industrial, ship, wire connection, anti-rust and anti-corrosion protection of solder joints, electronics components insulation, and protection treatment. Also works well for protecting headphones and phone cables
✓Note: To ensure that you order the correct size of Heat Shrink Tubing, Please confirm the exact diameter you need before buying to ensure that it will fit properly. Note: 6.4 mm (1/4") is the diameter of the round shrink tube before it shrinks
