Heat Shrink Tubing with Adhesive

Dual-Wall Heat Shrink Tubing with Adhesive provides a durable, waterproof, and insulated seal for electrical connections, wire splices, and battery terminals. When heated, the inner layer of heat-activated adhesive melts and bonds to the underlying surface, creating a strong, protective seal against moisture, dust, and mechanical stress. Ideal for use in automotive, marine, industrial, and battery pack applications.
Available from Marsen Energy in 3.2mm, 6.4mm, 9.5mm, and 12.7mm diameters (before shrink).

Price range: $3.20 through $5.30
