Black 6mm Heat Shrink 3:1 w/Adhesive | 15 cm x 5 Pcs.

This set of five 15 cm lengths of black 6 mm heat shrink tubing offers a reliable solution for sealing and insulating electrical connections. Each piece is crafted from adhesive-lined polyolefin, which not only shrinks to one-third of its original diameter but also creates a watertight, durable bond around wires and terminals. Ideal for automotive repairs, marine electronics, or any environment where moisture and corrosion are concerns, this tubing ensures long-lasting protection for your splices and connectors. The 3:1 shrink ratio accommodates a wider range of component sizes compared to standard 2:1 tubing, making it versatile for various applications. The internal adhesive melts during heating, forming a robust seal that resists pulling and environmental stress. With a 6 mm diameter before shrinking, these sleeves suit wires and cables up to approximately 2 mm in diameter after full contraction. Simply slide the tube over the connection, apply heat with a hot air gun or lighter, and watch it conform tightly. This pack provides ample material for multiple small projects or repairs, offering a cost-effective way to maintain professional-grade insulation and strain relief in your electrical work.
