Quick 4:1 Shrink Ratio: When heated, the heat shrink tubing shrinks to 4 times its original diameter, offering a tighter and more secure seal compared to the 3:1 tubing. Shrink Temperature: 80-120°C (176°F-248°F), ensuring your wires are instantly connected
Dual-Wall Adhesive Lined Heat Shrink Tubing: During heating, the outer heat shrink tubing tightly contracts, while the inner adhesive layer melts, sealing the connection area. It provides a tight, long-lasting seal that ensures superior insulation, waterproofing, and dust protection
Better Protection: The 4:1 heat shrink tubing, made from high-quality polyolefin, provides excellent electrical insulation, anti-friction, high-temperature durability, and water & oil proof protection
Widely used: The 4:1 heat shrink tubing is widely used in industries like power, electronics, telecommunications, automotive, and marine. It's ideal for insulation, sealing, and cable protection applications
Variety of Sizes: 5/32", 1/4", 5/16", 1/2", 5/8", 0.7", 3/4", 1", 1-1/4", 1.4", 1-1/2", 2". Note: The dimensions in the description refer to the size before shrinking, which is the diameter of the heat shrink tubing in its unshrunken, round state
