Grayline AL2X is a dual-wall, flexible heat shrink tubing composed of polyolefin with an adhesive lining. This product features a 2:1 recovery ratio, making it suitable for applications requiring precise fit and insulation. When exposed to heat, the outer wall rapidly contracts while the inner adhesive layer melts and flows, creating a watertight seal. AL2X is engineered to provide reliable protection and insulation in environments where moisture resistance is critical. This versatile tubing offers effective wire management and component protection for various industrial applications, combining the benefits of standard heat shrink tubing with enhanced sealing capabilities.
