The F3503/8-CL103 is a heat-shrinkable tubing designed for electrical insulation and protection applications. Constructed from irradiated Polyvinylidene Fluoride (PVDF), it features a minimum supplied internal diameter of 0.375 inches that reduces to a maximum of 0.187 inches upon recovery, achieving an approximate 2:1 shrink ratio. The tubing is rated for a wide operating temperature range of -55°C to 175°C and is recognized by UL for use at 150°C and 600 VRMS. Its high tensile strength, chemical resistance, and excellent abrasion resistance make it ideal for protecting wires, cables, and components in demanding environments.
