Grayline's AL3X is a dual-wall, flexible, heat-shrinkable polyolefin tubing designed for applications requiring robust waterproofing and enhanced adhesion. The product features a thick adhesive lining that melts and flows upon heating, while the outer wall simultaneously shrinks, creating a watertight seal. AL3X offers a 3:1 recovery ratio, making it suitable for projects demanding greater coverage or accommodation of larger size variations. This polyolefin tubing is engineered to provide superior protection and insulation for wires, cables, and connections in demanding environments where moisture resistance and strong bonding are critical.
