3:1 Dual Wall Adhesive Lined Heat Shrink Tubing

Adhesive lined heat shrink tubing is made from the co-extrusion of polyolefin and hot-melt adhesive. It is UL and CSA certified, RoHS compliant, and formaldehyde-free.

The 3:1 automobile special grade heat shrink tube features a unique white hot melt adhesive for enhanced sealing. It ensures long-lasting protection, keeping your equipment safe over time.

Glue-lined heat shrink tubing provides excellent electrical insulation and sealing properties. Additionally, it offers resistance to corrosion, moisture, water, and high temperatures. Furthermore, it is anti-aging, tough, and not easily prone to breakage. As a result, it is widely used in industries such as shipping, wire linking, and for anti-rust and anti-corrosion protection.

Application of 3:1 Dual Wall Heat Shrink Tubing

Dual wall heat shrink is perfect for sealing or protecting electrical splices and cable terminations. It also provides reliable protection for joints that require electrical insulation and waterproofing.3-to-1 heat shrink tubing is designed for connector-to-cable sealing, providing a reliable solution for repairing most damaged cable jackets without the need to remove connectors. This tubing shrinks to one-third of its original size when heated, ensuring a tight and secure fit. It provides protection against environmental factors such as moisture, dust, and abrasion around connectors and cables. It is ideal for quick, effective repairs and enhances the durability of cable connections.
