The F221V1/16-BK001 is a general-purpose, heat-shrinkable tubing from the FIT-221V series, constructed from durable cross-linked polyolefin. It features an approximate shrink ratio of 2:1 and is designed to operate within a wide temperature range of -55°C to 135°C. The tubing requires a minimum temperature of 90°C to begin shrinking and achieves full recovery at 121°C. With high tensile strength, excellent dielectric properties, and compliance with UL, CSA, and military specifications, it provides reliable performance. This tubing is ideal for applications requiring insulation, strain relief, wire bundling, and identification for electrical components and cables.
