Dual wall heat shrink tubing

DSG-Canusa's dual wall heat-shrink tubes are made to seal and protect your applications against moisture and corrosion and enhance their mechanical properties. Dual wall or double wall adhesive heat-shrink tubes are extruded with an inner layer of adhesive. Upon recovery, the inner layer of adhesive melts, encapsulates and bonds to the substrate, thus providing environmental sealing against moisture. Our dual wall heat-shrink tubing is available in standard dimensions, metric and imperial sizes, as well as many custom designs, colors and prints. With our extensive experience, innovative technologies and material expertise, we can meet your needs and develop a reliable and safe solution for every project.

Applications for dual wall heat-shrink tubing

Dual wall heat-shrink tubes are most frequently applied on terminals, connectors and splices where moisture ingress can affect electrical performance and initiate corrosion. Dual wall shrink tubing is perfect for hermetic sealing, water blocking, and sensor encapsulation to extend the life of your application in high-stress environments. Clear dual wall heat-shrink tubes have the additional benefit of allowing visual inspections of many critical applications. Our dual wall heat-shrink tubing meets automotive standards as well as VG standards for the aerospace and defense markets.
