The FITFAB-4-BK004 is a heat-shrinkable tubing designed for robust protection of wires and cables. Constructed from a durable blend of polyethylene and polyester fabric, this tubing features an approximate 2:1 shrink ratio. It is supplied with a minimum inner diameter of 1.575 inches and shrinks to a maximum recovered inner diameter of 0.787 inches, with a nominal recovered wall thickness of 0.040 inches. The tubing operates within a temperature range of -40°C to 125°C and achieves full recovery at 135°C. Being halogen-free, flame-retardant, and RoHS compliant, it is well-suited for applications requiring abrasion resistance and component bundling.
