Quadrios 23CA178 Adhesive-Lined Heat Shrink Tubing 3:1 Black 12mm x 5m

Unlike standard heat shrink tubing, the Quadrios 23CA178 features an inner adhesive lining that melts during shrinking to create a waterproof, strain-relieved seal. With a 3:1 shrink ratio, it conforms tightly over irregular shapes, connectors, and splices. The black cross-linked polyolefin construction is flame retardant, UV resistant, and halogen-free, making it suitable for demanding electrical insulation and cable bundling tasks.

Highlights

• Adhesive-lined for environmental sealing and strain relief
• 3:1 shrink ratio for tight, secure fit over varied diameters
• Supplied in a 5 m length, inner diameter 12 mm before shrinking (recovers to 4 mm)
• Operating temperature range: -55 °C to +125 °C
• 600 V dielectric strength, self-extinguishing, UV and chemical resistant

In daily use

Slide the tubing over the connection, apply heat above +110 °C, and the tubing shrinks while the adhesive flows to fill voids and block moisture. Ideal for automotive, marine, and outdoor electrical repairs where vibration, water, or corrosion are concerns.
