TE Connectivity NB09282001 Heat Shrink Tubing, Dual Wall, 3:1, 12mm ID, 3mm Shrunk, Black, ATUM Series

• Expanded Inside Diameter (Min): 12 mm [0.472 in]
• Recovered Inside Diameter (Max): 4 mm [0.157 in]
• Easier, lower cost installation compared to dip-coat processes
• Reduced production times – tubes can be bent or formed on the pipe.
• Moisture proof sealing – hot-melt adhesive flows between tubing and substrate to provide a permanent waterproof bond.
• Application versatility – one size of tubing fits a range of substrate diameters minimizing inventory costs.
• RoHS/ELV compliant
• Continuous operating temperature from –55°C up to +110°C
• Minimum shrink temperature: +80°C
• Minimum full recovery temperature: +110°C

Semi-flexible, heat-shrinkable tubing with a meltable adhesive inner lining designed to provide moisture proof sealing to a wide range of substrates such as electrical wire splices, cable jackets, wire breakouts and electrical components.

The high shrink ratios mean that only seven sizes are required to cover a wide range of substrate diameters. Typical applications are environmental sealing of electrical components including wire splices and harness breakouts as well as sealing cable ends against moisture ingress.
