SELTERM 1" Black [50 Feet] Marine Grade Heat Shrink Tubing Roll, 3:1 Ratio Dual Wall Adhesive Lined Waterproof Heat Shrink Wrap Tube, for Battery

SELTERM 1" Black [50 Feet] Marine Grade Heat Shrink Tubing Roll, 3:1 Ratio Dual Wall Adhesive Lined Waterproof Heat Shrink Wrap Tube, for Battery

3:1 HEAT SHRINK RATIO: Dual-wall heat-shrink tubing will shrink down to 1/3 of its original size when heat is applied, perfect for wire terminations or exposed insulation. The melting adhesive forms a waterproof, hermetic seal with >10.4 MPa tensile strength and 15 kV/mm dielectric strength, ensuring durable, insulated connections even in harsh environments. HIGH QUALITY FOR VERSATILE APPLICATION: This 1" high-quality heat-shrink tubing with adhesive is ideal for industrial repair, marine, automotive, wire bundling, electrical insulation, and DIY car audio. It protects solder joints from rust and corrosion while offering mechanical durability. With an operating temperature range of -55℃ to 125℃, it ensures reliable performance in extreme conditions. HOW TO USE: 2 easy steps to seal the connections. 1. Cut the heat shrink tube in the length you required from the roll and slide it over your connection point. 2. Use a heat gun or hot air blower to shrink the tubing at its full shrinkage temperature of 120℃ to seal the connection. That's it! Enjoy the peace of mind that comes with a secure, airtight seal. DURABLE & RELIABLE PROTECTION: The heat shrink tubing roll is perfectly sized at 1", offering ample length for various applications. It provides a secure fit for your wiring needs and ensuring reliable protection against abrasion, moisture, and environmental damage. PACKAGE CONTENTS: This package includes a 50 feet roll of 1" black dual wall polyolefin adhesive heat shrink tubing, providing secure insulation and protection for your wiring projects.

Protect and insulate your wires, connections, terminals, and splices with Selterm Heat Shrink Tubing Roll. This versatile product is perfect for long-lasting protection for bundling and protecting loose items. Also, this assorted dual wall heat shrink tube solves the problem of providing reliable and long-lasting protection for electrical connections or components from various environmental factors such as moisture, corrosion, abrasion, and physical damage and prevents electrical shock and fire hazards.

Our large heat shrink tubing features dual-wall construction with an inner wall of adhesive that melts and flows when exposed to heat, shrinking to 1/3 of its original diameter. This allows the tubing to conform to the shape of the object inside and fill any voids or air gaps. Once cooled, the adhesive hardens to provide an environmental seal, protecting your items from moisture and contaminants.
