About this item

• Complete Size Assortment: This shrink tubing kit contains 7 common sizes to meet most daily wiring repair demands. All 420 pcs are precut into 1.77" and 3.54", no need to stack two pieces. Each size is bagged individually to prevent mixing
• Dual Wall & Adhesive Lined Design: After heated, the inner glue melts to form a fully airtight seal to provide shielding from dirt, water and corrosion. The tubes are made of premium polyolefin. They are flexible, durable, and crack-resistant after long-term use
• Fast & Tight Connection: Using a heat gun or lighter, evenly heat the shrink tube for a few seconds. It shrinks to 1/3 of its original diameter for secure wire connections
• Wide Application: Suitable for automotive wiring harness, marine boat cables, motorcycle modification, RV electrical connection, RC model wires and household electrical repairs. Sluofeik shrink wrap tubing effectively insulates wires against water, salt spray and abrasion
• 3:1 Shrink Ratio Technology: Features a 3:1 shrink ratio that allows the tubing to accommodate a wider range of wire sizes and irregular shapes while maintaining a tight seal after heating
