Quadrios 23CA176 Adhesive-Lined Heat Shrink Tubing, Black, 3:1, 12.7 mm, 5 m

For electricians and technicians sealing cable splices in harsh environments, the Quadrios 23CA176 heat shrink tubing provides a waterproof, adhesive-lined barrier. This black polyolefin tubing shrinks at a 3:1 ratio to tightly conform to irregular shapes, while the inner adhesive melts to create a moisture-proof seal. With a pre-shrink diameter of 12.7 mm and a length of 5 m, it suits automotive, marine, and industrial wiring repairs.

Why choose it

The adhesive lining provides a durable, waterproof seal that protects connections from moisture, corrosion, and mechanical stress. Its 3:1 shrink ratio allows it to cover components with varying diameters, reducing the need for multiple tubing sizes. The wide temperature range ensures reliable performance in both freezing and high-heat conditions.

Ideal use cases

• Sealing and protecting cable splices in automotive wiring harnesses
• Waterproofing electrical connections in marine and outdoor equipment
• Insulating and strain-relieving joints in industrial control panels
• Repairing damaged cable insulation in harsh environments

Good to know

For best results, use a heat gun to apply even heat until the tubing fully recovers and the adhesive flows. The tubing is RoHS compliant and suitable for use in a wide range of electrical insulation applications.
