The Ancor 305148 adhesive lined heat shrink tubing is designed for reliable electrical insulation and strain relief in various applications. Measuring 1/2 inch in diameter and 48 inches in length, this black tubing is ideal for protecting and sealing wire connections on projects requiring a snug fit and durable performance. Once shrunk, the tubing reduces to approximately 5/32 inch, ensuring a tight seal around the wire bundle. The heat activated adhesive lining creates an impervious barrier against salt water, oils, acids, and UV exposure, making it suitable for both marine and industrial environments. Constructed from cross-linked polyolefin, this tubing offers superior strength compared to PVC and resists burning or melting during heat application. It features a high shrink ratio—shrinking to one-third of its original size at 257°F (125°C)—and maintains operational integrity across a temperature range from -40°F to 230°F (-40°C to 110°C). UL 224 compliance ensures safety and quality standards are met. This product is perfect for insulating wire splices, harnesses, and cable assemblies where environmental resistance and strain relief are critical. The packaging includes a single 48-inch section, providing ample material for multiple applications or repair tasks. Trust Ancor’s quality to deliver durable, professional-grade heat shrink solutions that enhance reliability and safety in your electrical work.
