Dual Wall Tubing is manufactured from a co-extrusion of flame-retardant, flexible, 3:1 shrink ratio heat shrinkable tubing with a special adhesive lining. When the tubing is heated, the adhesive lining melts and flows to form a positive environmental seal. The lining adheres to the outer tubing and the surface below, creating an excellent barrier to moisture penetration. Typical applications include the sealing and insulation of electrical splices, terminations, connector back shells, battery terminals and repairs to damaged cable. Due to the tubing’s flexibility, high shrink ratio and the wide variety of surfaces to which the adhesive will bond, the product is excellent in areas requiring corrosion and mechanical protection.
