ThermOsleeve Plus 0.427" Dual Wall Heat Shrink Tubing, 6" Length, 10-Piece, 4:1

Protect, insulate and seal automotive wiring, electrical connections, wire splices and cable assemblies with ThermOsleeve Plus 0.427" semi-rigid dual wall heat shrink tubing.

ThermOsleeve Plus is designed for demanding automotive and electrical applications where reliable environmental sealing is important. Its dual wall construction combines a semi-rigid, flame-retardant polyolefin outer jacket with a specially formulated adhesive inner layer.

When heated, the adhesive inner layer melts and flows around the connection, helping create a watertight barrier against moisture, automotive fluids and water wicking. This helps protect wiring and harnesses from corrosion and environmental damage.

With a 4:1 shrink ratio, this tubing can accommodate a broad range of connection sizes while providing a secure, professional finish.

Specifications

Why Choose ThermOsleeve Plus?

Standard single-wall heat shrink tubing primarily provides insulation and mechanical protection. ThermOsleeve Plus adds an adhesive inner layer that flows during heating to help seal the connection against moisture and automotive fluids.

The 4:1 shrink ratio provides additional flexibility when protecting connections with significant differences in diameter, while the semi-rigid outer jacket provides durable protection for automotive wiring and electrical systems.
