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.
