The FIT3503/8-CLEAR-25X4 is a clear heat-shrinkable tubing constructed from irradiated Polyvinylidene Fluoride (PVDF). It features an approximate 2:1 shrink ratio, with a minimum supplied internal diameter of 0.375 inches that shrinks to a maximum recovered diameter of 0.187 inches. This tubing has a nominal recovered wall thickness of 0.012 inches and is rated for a wide operating temperature range from -55°C to 175°C. It is UL recognized for 150°C and 600 VRMS applications and meets the VW-1 flame test, making it suitable for providing insulation and strain relief in demanding electrical environments.
