Quadrios 23CA179 3:1 Adhesive-Lined Heat Shrink Tubing, Black, 12.7 mm, 5 m

This heat shrink tubing stands out with its integrated hot-melt adhesive lining, which creates a moisture-tight seal when shrunk—ideal for protecting electrical connections in demanding environments. With a 3:1 shrink ratio, it conforms tightly over irregular shapes, providing reliable insulation and strain relief.

Highlights

• 3:1 shrink ratio for secure fit over connectors and splices
• Adhesive lining seals against moisture and contaminants
• Black polyolefin construction with UV and chemical resistance
• 5 m length, 12.7 mm inner diameter before shrinking
• Operating temperature range from -55°C to +125°C

In daily use

Simply slide the tubing over the connection, apply heat from a hot air gun or similar tool, and watch it shrink to about one-third of its original diameter. The adhesive melts and flows to fill voids, creating a durable, water-resistant barrier. It is suitable for automotive, marine, and industrial wiring repairs, as well as cable bundling and strain relief.
