Quadrios 25CA498 Adhesive-Lined Heat Shrink Tubing, Transparent, 3.2 mm Diameter, 1.2 m Length, 2:1 Shrink Ratio

This adhesive-lined heat shrink tubing stands out by combining a transparent, cross-linked polyolefin outer wall with an inner adhesive layer that melts during shrinking to create a moisture-resistant seal. Unlike standard tubing that only provides mechanical protection, the adhesive bonds to the underlying surface, sealing out water, dust, and corrosive fluids in automotive, marine, and outdoor electrical work.

Highlights

• Transparent tubing allows visual inspection of the covered connection or splice after installation.
• Adhesive lining flows into voids and irregularities, providing environmental sealing and strain relief.
• 2:1 shrink ratio recovers tightly over connectors, terminals, and wire splices with uneven shapes.
• Cross-linked polyolefin resists common solvents, oils, and chemicals, and remains flexible from -55°C to +125°C.
• UV resistance makes it suitable for outdoor exposure without rapid degradation.

In daily use

Slide the tubing over the joint, apply heat evenly with a heat gun, and watch it shrink to 1.6 mm inner diameter while the adhesive flows to fill gaps. The transparent wall lets you confirm the adhesive has fully wetted the surface and that no air pockets remain. The 1.2 m length can be cut into multiple pieces for dozens of small repairs or harness branches.
